I have a Windows Server 2012 R2 Standard that has been in service for about 3 years; all updates installed are installed. All domain users are Windows 7 Pro 64-bit and connected to the network with CAT5 ethernet. In the last week, some users started experiencing slow browsing when saving to shared folders on the server. If the user opens a file from the shared folders, it is normal access speed. The slowness exists when the user wants to save a file and browses to a shared folder, it takes 25-30 seconds for the folder list to propagate. Once the list is propagated, maneuvering to another folder and saving is normal access time. This happens from all applications--Office, Adobe, etc.
If I create a shortcut to a folder within the shared folders, access seems to be relatively quick, but there are lots of folders and files within the shared folder the users need to access.
I have uninstalled anti-virus on the server to make sure that wasn't causing the lag times. Also, disabled anti-virus on the user computer to test if it made any difference in access times.
Thanks for advice.
That could be anything but the first thing I would look at is drivers for the network adapter in the server. Are you sure it is not CAT5e? CAT5 is slow.
Thanks for your response. Yes, it is CAT5e. I have checked drivers for network adapter and it is updated. I don't understand why browsing to open files is normal response while browsing to save a file is slowed. Is it possible that too many files/folders on a drive could be the issue?
One of the possible solutions is this How To Fix Windows Server Network Performance Problems -- Redmondmag.com. Can you try that?
Thanks! I will check this.
