SQL [sqlservr.exe] Memory Consumption on Small Business Server July 7, 2009

Posted by Gomez in IT, Microsoft, Performance & Alerts.
Tags: , , , ,

I started receiving alarms that pages/sec on my client’s SBS Server was 6952.92 pages/sec. Please note that Microsoft Best Practices recommends no more than 20 pages/sec.
I found that sqlservr.exe was consuming in excess of 1.5GB of memory. This is been a known issues for Servers running Small Business Server, I will walk you through the process of reducing usage for this memory thirsty process.

1. Open Task Manager > Processes Tab, View Menu > Columns, select PID check box.
2. In the list of processes locate the sqlservr.exe process that is consuming the most memory (there might be multiple instances of sqlservr.exe) take note of the PID number next to the memory thirsty process.
3. Open a command prompt and issue the following command without the quotes,
    “tasklist /svc” (this is used to display running processes (PIDs) and applications)
     next to the PID number previously identified in taskmanager take note of the service name.
   The service would be MSSQL$SBSMONITORING.

4. At the command prompt issue the following commands, after each command press enter;
 Command 1: osql -E -S SERVERNAME\sbsmonitoring  
(replace SERVERNAME with the hostname of your server, sbsmonitoring is the service name )
 Command 2: sp_configure ‘show advanced options’,1
 Command 3: reconfigure with override
 Command 4: go

Command 1: sp_configure ‘max server memory’, 200
(200 represent memory size in MB, replace 200 with any memory size you wish, default is 2147483648)
 Command 2: reconfigure with override
 Command 3: go

 After the last command “Go” you should see a confirmation that DBCC execution has completed. You can just type exit at the command prompt to exit.Open Task Manager > Process Tab and review the sqlservr.exe and confirm that memory usage has decreased.
Best of luck..

Every month now, GLUG meets up to discuss and share ideas.  Last GLUG meeting I volunteered to do an installation of SNORT on CENTOS and live demonstration.  It was a privilege to contribute to such a growing community in Guyana. Also Mike Harrison of Utiliflex took part to offer us his valuable experience and motivation.

Quick guide to setup a linux DHCP server on a network, you can modify this to work with your own design.

[root@dhcp ~]# yum install dhcp

[root@dhcp ~]cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
cp: overwrite `/etc/dhcpd.conf’? y
[root@dhcp ~]vi /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;

subnet netmask {

# — default gateway
option routers        ;
option subnet-mask    ;

#option nis-domain               “akeung.com”;
option domain-name              “akeung.com”;
option domain-name-servers;

option time-offset              -18000; # Eastern Standard Time
#       option ntp-servers    ;
#       option netbios-name-servers;
# — Selects point-to-point node (default is hybrid). Don’t change this unless
# — you understand Netbios very well
#       option netbios-node-type 2;

range dynamic-bootp;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
#        host ns {
#                next-server marvin.redhat.com;
#                hardware ethernet 12:34:56:78:AB:CD;
#                fixed-address;
#        }

Then esc, press


To start the service :

service dhcpd start

To enable it at bootup :

chkconfig dhcpd on

You can locate the leases at :


Also, if a reservation is needed. Simply add the following to /etc/dhcpd.conf

host daakeung {
option host-name “daakeung.akeung.com”;

Cisco Dual Wan Fail-Over using SLA Tracking July 3, 2009

Posted by daakeung in Cisco, IT.

Maintaining a high availability connection is critical in any modern network infrastructure.  Some would have access to the internet via multiple ISPs.
In most cases where the ISPs would not peer via any routing protocol, customers are left to setup fail-over with static routes.
There are two types of failures:
  1. Physical : the router would detect one of its interface not connected, invalidated any next hop routes through it. In turn move to another valid route with a higher metric.
  2. Logical : the router has it’s interface online, but somewhere along the path it has to take to reach the destination is unavailable.
Basic router commands with higher metric will not fail-over with a logical failure.
Using SLA Tracking, we can accomplish this.
Consider the following diagram and configuration:
Cisco Dual WAN

Cisco Dual WAN

Cisco IOS used: c181x-adventerprisek9-mz.124-24.T

! Identify the SLA.
ip sla 10

! Set up the IP address to ping, in this case yahoo.com ip.

! Set how long in milliseconds to wait for a reply.
timeout 1000

! Repeat Rate.
frequency 3

! Start SLA 10 from now to forever.
ip sla schedule 10 life forever start-time now

! Setup track 10 to sla 10 for reachabilty.
track 10 ip sla 10 reachability

! Setup route for testing reach ability to the internet.
ip route

! Setup primary link with track 10 parameter.
ip route track 10

! Setup fail-over link with higher metric.
ip route 20
Depending on your configuration, you will need to setup NAT on both interfaces.

How Save Outlook Auto Complete List June 18, 2009

I recently had a client who wanted to preserve their email list (auto complete cache), so here’s how to perform this neat little task.

Outlook 2003 and Outlook 2007 have a feature called Email Address Auto Complete. As you type in an email address into the TO:, BCC or CC: field outlook will display a list of matching email addresses from the outlook auto-complete cache.

 Example of Outlook Auto Complete

Ok now we know what auto complete is, let located the file;

Close Outlook.

Open Windows Explorer and enter the following address in the Address bar: %appdata%\Microsoft\Outlook (this is the same as drive:\Documents and Settings\username\Application Data\Microsoft\Outlook) Windows Explorer will update to the appropriate Outlook folder. In this folder you would see the .nk2 file(s). Now to explain every Microsoft Outlook profile will have its own .nk2 file e.g. the default profile name is outlook so you will see the outlook.nk2 file. Just make a copy backup of this file, that’s all to it, you are done!

 If you are not too sure what your current profile(s) are you can open mail icon in control panel and on the Mail Setup – Outlook dialog box, client on Show profile, here you can see all your default profiles.

Now let’s say that on the computer you want to restore/replace the outlook.nk2 file has a different profile name e.g. exchangepro is the name of the profile on the target computer, all you need to do is navigate to: %appdata%\Microsoft\Outlook, paste the outlook.nk2 file then rename it to profilename.nk2 (in this example exchangepro.nk2). Open Microsoft outlook and enjoy.

ITunes has detected an iPod in recovery mode on Windows PC June 13, 2009

Posted by Gomez in Apple.

FIRST: This minor issue could give someone with love for music headaches so I am sharing my experience/ solution with you.

Now if you follow ITunes recommendation to restore your IPod, that’s ok, but it will never stop asking to restore your IPod. Remember a restore is a factory default, so all of your files would be wiped!

SOLUTION: This iPod error message is caused when you have a removable device other than your iPod plugged into a USB port and occupying the drive letter the IPod previously used. All you need to do is unplug all removable USB devices, Open Computer Management > Disk Management, look for  your IPOD device ,right click on your iPod device and click change drive letter, assign a new drive letter to your IPOD device, after successful change, unplug IPOD data cable, and reconnect the cable. Your IPod would display as normal.

Where are my CALS? June 13, 2009

For all my fellow Small Business Server users, this week I was greeted with an issue with one of my client’s informing me that they are not able to access the mapped network drives “Connection to resource has exceeded maximum connections” After extensive searching in Event Viewer > System logs, I came across the following entry;

Event Type:        Error
Event Source:    SBCore
Event Category:     None
Event ID:              1023
Date:                     6/11/2009
Time:                     7:08:27 PM
User:                     N/A
Computer:          XXXXXX
The license store for the client access licenses is not valid. Only the minimum number of client access licenses will be available until a valid license store is restored. For more information, see Help in the Licensing snap-in.

 Open Server Management > Licenses, found that  installed CALs (50 Client access licenses) disappeared leaving only the default “5”. 

There are three main methods for restoring the License Store.

Method 1: If you had previously exported the license store after entering the CALS and activating them, you can simply restore that file.

Method 2: If you have the actual CAL codes you can re-enter and activate the CALS.

Method 3: If you have a backup of your system drive you can locate the file licstr.cpa which is located in %systemroot%/system32  folder. Simply replace this file on your affected system with the previously backed up licstr.cpa.  (This method was the one that worked in my situation)

Now after you have restored the licstr.cpa file in its original location, be sure to restart the license logging service.

Word of caution for those who have not experience this issue, take a backup of your license store!

If you need to seize roles from a failed server, you can do so by :

Opening run, type cmd then ntdsutil.

ntdsutil: roles
fsmo maintenance: connections
server connections: connect to dc1.akeung.com
Binding to dc1.akeung.com … Connected to dc1.akeung.com using credentials of locally logged on user.

Seize domain naming master    – Overwrite domain role on connected server

Seize infrastructure master   – Overwrite infrastructure role on connected server

Seize PDC                     – Overwrite PDC role on connected server

Seize RID master              – Overwrite RID role on connected server

Seize schema master           – Overwrite schema role on connected server

Select operation target       – Select sites, servers, domains, roles and naming contexts

Transfer domain naming master – Make connected server the domain naming master

Transfer infrastructure master – Make connected server the infrastructure master

Transfer PDC                  – Make connected server the PDC

Transfer RID master           – Make connected server the RID master

Transfer schema master        – Make connected server the schema master


This is the interesting part, to seize the roles to the connected server, issue the commands as follows:

fsmo maintenance:  seize schema master

fsmo maintenance:  Seize PDC

fsmo maintenance:  Seize RID master

fsmo maintenance:  Seize domain naming master

fsmo maintenance:  Seize infrastructure master

A prompt will confirm the change you will be making to active directory.  Please only use role seizure as a last resort when you cannot “TRANFER” a role.

Cisco OSPF and Windows RRAS OSPF May 24, 2009

I’ve been battling with getting Windows RRAS ospf and Cisco ios ospf to become neighbours for the past few days.

If you turn on ospf debug in windows and the following shows up :

Rejected an OSPF packet from x.x.x.x to because the OSPF data length in the OSPF header was 48 but the length calculated from the IP Header fields was 60.

You should disable the following on the cisco ios:

router ospf 100

no capability lls

Also, if you are running ISA with RRAS you should disable  “block fragmentation”
