Some of our users complain that especially in the morning they have to wait for quite a long time after they input their domain credentials into login window. Some of them wait for several minutes until they see desktop icons appearing, others have to wait to access network-based applications (Outlook configured for exchange server and other applications running from network shares). Others have to wait for a while when "Applying computer settings" windows is displayed.
All computers are Windows XP SP2 and all servers are Windows 2003 SP2
I've checked event log and noticed that most of them have the following events:
--------------------------

Type: Error
Event: 7023
Source: Service Control Manager
Description: The Computer Browser service terminated with the following error: Timeout. Operation failed (literal translation from Italian)

services.msc shows that 'computer browser' service is not running, however i can successfully launch it manually after logging in. I've applied the KB889320 but the issue is not resolved.

Netdiag errors common to most of these PCs are as follows:
DC list test . . . . . . . . . . . : Failed
Kerberos test. . . . . . . . . . . : Failed

How can I resolve the problem?
