I have two file servers running on VM both servers are on different physical servers.
Both connect with dfs namespace.
The problem part is both servers never have same copy speed.
Sometime very slow files copy about 1MBps on FS01 and fast copy 12MBps on FS02.
Sometime fast on FS01 and slow on FS02.
Sometime both of them slow..
So as usual I reboot the servers. Doesn't work.
Then I reboot the DC01 also doesn't work. There is another brother DC02.
After I reboot DC02, one of the FS become normal and another FS still slow.
FS01 and FS02 randomly. They never get faster speed together.
Users never complain slow FS because 1MBps is acceptable for them to open word excel etc.,.
The HUGE problem is I don't have backup when the slow FS days.
The problem since two weeks I'm giving up fixing it myself and need help from you expert guys.
Thanks!
DC01, DC02, FS01, FS02 (Win 2012 and All VMs)
