I have an odd problem that I am struggling to diagnose.
I have a Windows 2008 R2 Server and just a single workstation on the network, running Windows 8.1 Pro.
A lot of the time the workstation and server communicate normally, but from time to time it suddenly starts taking 5+ minutes to open a simple document on a share on the server.
When this happens all other server communications are fine, I can even RDC into the server and copy a file across at normal speed.
Normally when this happens, rebooting my workstation will fix it, but sometimes it doesn't and I have to reboot the server too. Occasionally even rebooting both won't help, and only time will fix the problem.
I originally thought my workstation was the problem as it had a dodgy SSD, but I replaced the SSD and did a full new install which appear to work for a couple of weeks, but now the problem is back.
Any ideas on how to start diagnosing this?
