Files very slow or unresponsive after migration

xav1963 used Ask the Experts™
Just had a very successful migration from SBS 2003 to SBS 2011. However, clients are complaining that takes a very long time to open up, modify and close shared files on server, even non-responsive at times. I log in with a network admin account and everything is lightning fast... so it is a permission issue.
I followed instructions and used robocopy with correct switches and files were copied over with correct permissions. But in order to see users in the SBS console, I had to change all their roles to "Standard" user role. I believe that caused the problem. I tried to test one folder and reapply a user's permissions on it and no change occurred.
How can I correct this? Thx...

Do you have an AV solution on the server which is doing real time scanning?

probably you have default  wait and retry switch.

Set both to zero.

Can you provide your robocopy script


No there is no AV installed on server yet...
The script is the one recommended by technet...

Robocopy \\<SourceServerName>\Users \\<DestinationServerName>\UserShares /E /COPY:DATSOU /R:10 /LOG:C:\Copyresults.txt

from migration guide

what do you mean by "have default wait and retry switch"?
Fixed by Microsoft... root issue due to many GPOs did not migrate over or were created during the migration. Also had to change ser roles again and be sure had membership of corresponding groups.


As mentioned, MSFT resolved for me.
