    Outlook Freezing After 2008 R2 Upgrade

    I need ickle bit of help, over Christmas we upgraded our 2003 domain up to a 2008 R2 domain! Its all gone swimmingly so far logon times are brilliant, group policy works great!

    This was until we decided to turn off one of the old 2003 demoted DC's we then got users complaining of outlook pausing every time they open an email for 30ssec or more. We have done hours of investigation, group policy is correctly redirecting and we have packet sniffed and the pc's do not connect or look to the server!!

    The only way to solve it is to delete the ntuser.dat! However I don’t want to open a the world of pain this would cause if deleted all users ntuser.dat!

    Does anyone have any suggestions on solving the pausing, if not the best way of resetting everyone’s ntuser.dat!!!

    Also we are a little cautious about taking the domain functional level up to 2008 R2 as we are worried about XP clients connecting, does anyone have this functional level and happy xp clients?

    Thanks

    mmm this is a weird one.. Our migration is the same as yours. We did not experience these problems. Sounds weird to me thats the problem lies into the ntuser.dat. Are you sure the correct DC are displayed into your exchange. system manager. Secondly did you recheck the global catalog properties on your DC's ?

    You could also start outlook with special command switches.

    We have a work around, we have shut down the server and put a DNS entry in with the old servers name pointing to on of the new dc's ip address! No pausing! We may do a profile purge over summer

    Function levels deal with how the DC's talk to each other it doesn't affect how clients communicate with the server. Our 2008 domain is at 2008 function level and XP and 2000 clients will still work.

    Note Network clients can authenticate or access resources in the domain or forest without being affected by the Windows Server 2003 domain or forest functional levels. These levels only affect the way that domain controllers interact with each other.

    As for the Outlook problem have you grabed a copy of an affected ntuser.dat file and loaded it into regedit? If not i'd do that and search it for the old server name you'll almost cretainly fild reference to it.
