SBS Console : No rights for creating Exchange mailbox
Oct 19th
Today a customer complained about the SBS console not completely working. The administrator’s account received an error no “rights for exchange”.
Although the user was a member of all the correct groups, the solution was simple. The domain admin account’s primary group membership was domain admins and should be domain users. Now everything is working fine!
Howto : quickly check domain health
Oct 18th
Before I upgrade a domain I usually check for problems and issues. I use the following steps to give me an idea of the status :
dcdiag /v
(Check DC en services)
netdiag /v
Check networking components
netsh dhcp show server
Show DHCP status
repadmin /showreps
Show all replication between sites
repadmin /replsum /errorsonly
Show replication issues
When you perform the steps mentioned and you didn’t ran into several errors than you have probably nothing to worry about. 
VSS error FAILED: Unable to create a VSS snapshot of the source volume(s).
Oct 13th
I ran into a problem with VMware converter. I got the following error :
unable to create a VSS snapshot of the source volume(s). Error code: 2147754774
The following steps worked for me :
Confirm that there are no errors with the following command :
vssadmin list writers
I found more then one provider with the following command :
vssadmin list providers
I deleted the second (everything but the first) provider (please back-up your keys first!) :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers
I then did a restart of the VSS service (net stop vss , net start vss)
Followed by enabling shadow copies (and made a snapshot of the drive)
Now I was able to succesfully create VSS and import a running physical machine using VMware converter!

Robocopy Error #112 when copying large amount of data to EMC cifs
Jul 14th
A customer had problems synchronizing large amount of data to an EMC CIFS share using the robocopy /mir commandline option.
2011/07/14 13:38:58 ERROR 112 (0x00000070) Creating Destination Directory \\xxxx\xxx\ There is not enough space on the disk. Waiting 30 seconds...
After some troubleshooting I found that opslock, hidden sharing and CIFS caching were not the problem but the fact that the share was thin created. I created 2 shares, one thin and one fat. You guessed it right, the thin version failed. Changed the properties to fat and the problem was gone!
