We have been running a HP Windows 2008 Storage Server for several years without any problems. However recently every 5-6 days the share access goes really slow (snail pace).
Once rebooted the system goes back to normal for another 5-6 days.
The network cards are teamed but I have also tried as standalone. Also I have turned off / on the recommened TCP settings for Windows 2008.
Any triubleshooting help or guidence very much appriciated.
