[gptalk] Re: Long logon times when switching between metaframe servers.

As you state they logon to two different servers, does it also happen if they 
logon to two servers in the same OU? Or only if they logon to another farm or 
silo server(s).

Hello, 
I'm a litlle plagued by this annoying problem. Our metaframe people are 
complaining about long logon times for GPO's for certain servers. 
I've studied their userenv logs and found it relates to following behaviour. 
I've got loopback processing enabled with merge, and it merges several more 
restrictive settings when logging on to a metaframe server. 
When a user logs on the first time al his gpo settings are applied which takes 
about 30 seconds, when they logon a second time to the same server their 
settings are marked "same" and the application is skipped. 
This is how it should work obviously. Now when they logon to another server in 
the metaframe farm i see NTuser.pol from their profile first erasing all 
settings in the registry extension part, and then reapplying them again from 
the GPO on the domain. 
Only the registry extension has this behaviour , all the other ones don't do 
this. 
Why does this happen? and why is the gpo history not transferred via the 
roaming profile to another server ? Can this be reversed somehow ? 
Even if in userenv it says: "the lists are the same" it still deletes and 
reapplies. 
see example 
USERENV 14:34:43:370    ProcessGPOs     Processing extension Registry   4.906 
USERENV 14:34:43:370    ReadStatus      Read Extension's Previous status

and then the reapplication

SetRegistryValue        NoSMMyPictures => 1  [OK]       7.859 
normally it should be like this (same user again on same server) 
USERENV 14:12:54:275    ProcessGPOs     Processing extension Registry   1.359 
USERENV 14:12:54:275    ReadStatus      Read Extension's Previous status 
successfully.  1.359 USERENV 14:12:54:275    CompareGPOLists The lists are the 
same. 1.359 USERENV 14:12:54:275    CheckGPOs       No GPO changes and no 
security group membership change and extension Registry has NoGPOChanges set.   
  1.359
USERENV 14:12:54:275    ProcessGPOs     ----------------------- 1.359 
As we have multiple metaframe's in multiple farms and silo's this actually mean 
that mostly all of these settings are constantly being reapplied costing the 
user 30 seconds every time.
If anyone can shed some light on this it would be greatly appreciated. Thanks
