SP3 and Dell NAS

[jeff]

I have Dell 4400 configured as a DC using active directory
and a Dell 740N as a NAS. I access the NAS via mapped
drives. I installed SP3 and critical updates to the DC
and now no users can access the mapped NAS drives. Error
messages include notices that passwords and/or usernames
are incorrect and that device is already in use.

Dell was unable to help and referred me to Microsoft.

Any Suggestions?

Other than the usual reboot, try removing it from the domain and readding it
back...
