I have a problem when i try to log on from my pc to AD in the domain.
When i boot the pc, and enter username, password and domain to which i want to log on, i need to wait 3-4 minutes, at Applying your personal settings... pop

Any ideas, solutions?

How many computers have this issue? Do any logon with out any problems?
You could try a gpupdate /force from the command line see if gives any new errors.
You could also try resetting the computer account on the domain. From a server you can type:
netdom reset [computername /domain domain.net /UserO [local user account on PC] /PasswordO *
If that doesn't work, check the event log on both the local PC and on the server
If it still doesn't work after that, I might taking it off the domain and readding it just as a test to see if that has any affect on it.

When i tried gpupdate/force, it generates the same two logs.

I reset computer account throught Active Directory users and computers, then add the computer name to my user, and again the same problem.

???

login locally check IP addressing , DNS etc

also try pinging the workstation via the server

I solve the problem :)

Thax for the advices.

I log to DC and try to ping my pc, but i coulnd't, Requiest time out.

Then i remember that i have Firewall client and Comodo Firewall on my local pc.
I uninstall Comodo firewall, restart the pc, and now everything is ok.
It log on for less than 15-20 sec.

Thax a lot for the advices.
