Vista\2008 SP2

This has been RTM for a while, and I was expecting it to show up on Windows Update today, but it didn't. I downloaded it from Technet but just noticed it on the Microsoft main site here.

I particularly like the combined Vista\2008 32bit\64bit DVD here.

How to get the latest build of Chrome

Hacked off by the fact that IE8 has stopped responding my system, and not wanting to reboot right, I decided to start using Chrome again.

I has been using the beta builds before but forgot how to get them.

You can find out how here:

Isinteg fails to run on Exchange 2007 with Error: FULLCHKMGR::EcReadRowCountGlobalFlag failed with error JET_wrnColumnNull

I had a corrupted mailbox, so created a temporary store to move the mailbox into. I then wanted to run an isinteg on this store before returning the mailbox back to the original store.

The first part went ok, but when I went to run isinteg I received the following error in the logfile:
Error: FULLCHKMGR::EcReadRowCountGlobalFlag failed with error JET_wrnColumnNull

Searching around prodeuced a few solutions, but none in English! I found the following post:
http://www.spurius.nl/?p=46

My Dutch isn't very good, but I surmised that the command to run was:
isinteg -s servername -fix -test rowcounts

I ran this, and indeed I could then run an isinteg with -test alltests. Thanks to whoever that blogger is!

Feb 2009 Hotfix Package for DPM 2007 (KB963102)

For some reason, my DPM server doesn't seem to pick up on updates from Microsoft, so I occasionally scan download.microsoft.com for any updates.

Today, I found a new hotfix download for DPM 2007:
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=8a551a13-270e-46c0-91ee-4a6d3d8bf034

It patches some issues detailed here:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;963102

Can anyone tell me how to make DPM 2007 register with Windows update on this server?

Communicator 2007 Automatic Sign-in Failure

In my case this was caused by lack of DNS entries.
Just creating a sip CNAME to my OCS 2007 server was enough, but there are others you can create.

I found a tool that helps you troubleshoot DNS issues here.

A\CNAME records:
  sip.domain.com
  sipinternal.domain.com
  sipexternal.domain.com

SRV Records:
  _sipinternaltls._tcp.domain,com
  _sipinternal._tcp.domain.com
  _sip._tls.domain.com

Communicator 2007 Fails to download corporate address book

In my case, this was caused by https certificate problems. The certificate had been generated during the install, but had not been applied to the IIS server.
Can also be caused by firewall issues with ports or IIS MIME issues for dabs (application\dabs) or lsabs (application\lsabs).

OCS 2007 Activation Problem

Failure to activate OCS 2007 during installation.
This can be based by having a space ( ) or quote (") character in the service account passwords.
Looks like the setup program does not quote the password correctly, so fails when either of these two charaters are used.

DPM 2007 SP1 Real Soon

Launched at the start of December 2008 apparently.
I'm not clear as to how the Hyper-V protection will work though - Will we have to pause Hyper-V guests or not during protection?

System Center Essential OpsMgr Error 0x80004005

After an install of SCE 2007, the OpsMgr service would not start and kept throwing an 0x80004005 error.
Found another blog with a fix:
http://blogcastrepository.com/blogs/brian_tucker/archive/2008/01/16/scom-opsmgr-2007-health-service-error-0x80004005-event-id-7023.aspx

It was a little different in my case, I had to remove LMIRfsClientNP from the registry key:
HKEYLM\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder\ProviderOrder

D-Link DCS-6620G - HTTP 400 Bad Request

After the install of Silverlight - My D-Link DCS-6620G camera started returning HTTP 400 Bad Request errors.
After a bit of investigation, I found this:
http://silverlight.net/forums/p/7452/77779.aspx

Locating the key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents, I removed a couple of XML document type I figured that I would never use.

Everything now works fine.

Kaspersky Internet Security 7 will not install

I'd forgotten this one... Something gets left in the registry so that the Kaspersky install keeps giving you this error:
"You must restart your computer before proceeding with the installation."

Download and apply this registry fix from Kaspersky.

Network connection keeps stopping in Windows Vista Ultimate x64

I've recently had an issue with my main desktop machine losing network connectivity overnight. No other machines are affected, only my desktop one. The problem computer is connected via wired ethernet to a Netgear GS105 Gigabit switch. The lights on the switch stay on, so there appears to be nothing wrong with the physical connection but the system still can contact nothing on the network.

 What has worked as a fix, was to go into the network connections, disable and then enable the LAN connection. The computer will then work fine for another 24 hours.

After some searching, I read this:
http://forums.techarena.in/vista-help/791873.htm

Which then led to this:
http://support.microsoft.com/kb/927168

Now, each time the connection has stopped working, I have had my Windows Mobile 6.0 phone plugged in, synchronising and charging. I wondered if this was the same as Internet Connection Sharing as the phone is given an IP and can access the network via my desktop computer. When I had network problems with my network camera, I do remember switching on RSS (receive side scaling) as part of the changes made to the IP stack.

I've disabled RSS for now using the command:
netsh interface tcp set global rss=disabled

I'll followup with any further lockups or not!

Poor performance with D-Link DCS-6620G and Microsoft Windows Vista - Solved

I recently bought a D-Link DCS-6620G IP camera to replace a failed Panasonic one. I found the performance to be terrible. After running a network capture I discovered the following:

My Vista desktop would send two TCP SYN requests with ECN and CWR flags set.
The camera would resond to each of these with a TCP RST.
My Vista desktop would then send a TCP SYN request without ECN and CWR flags and the camera would then respond normally.

This problem also meant that I could not add the camera to D-Link D-ViewCam Monitor as the request to add a camera failed with an unable to connect message.

After a bit of reading, I discovered the CWR and ECN flags were being set because I had ECN enabled in my IP stack. I verified this by running:

netsh interface tcp show global

Querying active state...

TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State          : enabled
Chimney Offload State               : disabled
Receive Window Auto-Tuning Level    : disabled
Add-On Congestion Control Provider  : none
ECN Capability                      : enabled
RFC 1323 Timestamps                 : disabled

Running the following, disabled the setting:

netsh interface tcp set global ecncapability=disabled

Ok.

And...

netsh interface tcp show global

Querying active state...

TCP Global Parameters
----------------------------------------------
Receive-Side Scaling State          : enabled
Chimney Offload State               : disabled
Receive Window Auto-Tuning Level    : disabled
Add-On Congestion Control Provider  : none
ECN Capability                      : disabled
RFC 1323 Timestamps                 : disabled

The camera is now working very well.

Microsoft DPM 2007 - Enable colocation of data on tape

If you have multiple storage groups with the same data retention policies, you can now colocate the data on the same tapes as long as you have installed the DPM 2007 feature pack. Most useful if you have a single drive rather than a library.

It's not settable in the GUI, but the following Powershell command turns it on:
Set-DPMGlobalProperty -DpmServer <DPM Server Name> -OptimizeTapeUsage $true

More details here.
