John-
20 seconds is not unheard of for something like IE maintenance. You can
actually drill into the time taken within IE maintenance further by using
its trace log, which you should find for a given user under
%userprofile%\Application Data\Microsoft\Internet Explorer\brndlog.txt.

That file should show exactly what is happening during IE Maintenance
processing.

As for the other error, that looks very much like a DNS issue, where the
correct DNS names are not being found and the machine is defaulting to NTLM
authentication. Does this happen on more than one client ? If so, then I
would suspect DNS on the server side. If not, then something with this
client. Maybe run DCDiag from the client and see if it shows any issues. Or
try using netdom to test the client's secure channel connection to the
domain. Maybe you just need to re-join the machine to the domain.

Subject: [gptalk] Understanding GP Processing

Hi,

As some of you may know I've been posting a lot lately, mostly in relation
to login times. I've been examining the userenv.log and am trying to
understand why certain extensions take longer to process. I am also seeing a
few errors which I'm not sure are causing an issue, are normal or maybe to
blame for the longer processing times. For instance here is part of a log:

USERENV(50c.bac) 08:55:35:513 ProcessGPOs: Processing extension Internet

USERENV(50c.bac) 08:55:56:066 ProcessGPOList: Extension Internet Explorer
Branding was able to log data. RsopStatus = 0x0, dwRet = 0, Clearing the
dirty bit

As you can see the Internet Explorer Branding policy started at 8:55:35:513
according to the log and didn't finish until 8:55:56:066. That's over 20
seconds to apply this extension and the policy which has the IEB settings
does not contain a great deal of IEB settings. 

This part here is also concerning:

USERENV(50c.bac) 08:55:40:787 ImpersonateUser: Failed to impersonate user
with 5.
USERENV(50c.bac) 08:55:40:787 GetUserNameAndDomain Failed to impersonate
user
USERENV(50c.bac) 08:55:40:803 GetUserDNSDomainName:  Domain name is NT
Authority.  No DNS domain name available.

A net helpmsg 5 indicates 5 is access denied, however I'm not sure in what
this means in this context. Can someone please shed some light on this
supposed error?
