We have been moving from Novell to Microsoft for a couple years company wide. Until now, other than outlook, the apps were all local with the data being moved from a Novell server to a 2008R2 server. A week ago we moved our final drive which was three apps the run .exe's from the server directories. Out of 300 PCs - all replaced in the last year based on ghosts - about 25 took ten minutes to run an app from the shortcut. All the other PCs don't have the trouble. I first went to that vendor but after troubleshooting, I realized they had slow connections to any windows drives. They were fine hitting the Novell drives. I'm guessing since they only pulled documents from the MS drives until now, the slowdown wasn't felt. Running the larger exe is where the problem started to show. I've tried many things I found online so far to no resolution. These things include:
autotuning set to restricted, normal or disabled
turned smb2 off/on
turned RDC off/on
set NIC to autonegotiate
Not server or switch based as good PC is sometimes in the cube right beside bad pc.
ran windows update
same NIC drv between good and bad PCs
Any ideas where to go next? Thanks for your help!
Do you have only internal DNS servers listed in the IP client settings (or option 6 from DHCP) of all workstations and servers?
Is the Novell client still installed?
Have you checked your Binding order in the network adapters window advanced settings dialog box?
Before going further, what’s the operating systems of these workstations?
