Virtual Svr16 Being slow and unresponsive

[DCUK6]

Our virtual file server is starting to become problematic.

 

On Friday it would let us login but kept hanging, it then wouldnt let us log in, stuck on welcome, wouldnt shut down.

Gave the hyper v host a restart, checked the raids and all ok and it came back up.

 

Its still very very slow. Server manager take 10 mins to finish scanning but report no errors.

 

CPU is at 5%, RAM is 1.4/4gb so plenty remaining. (2.6gb Available its showing)

 

I just cant find anything wrong with it but its not happy at the minute.

 

Looking through the event viewer takes forever and a day to load.

 

Any ideas of things to check?

Provisioned disk space ??

Check the host server logs for any issues. Might help indicate an issue

I/O on the host?

Check Write Back Cache is enabled.

Host logs only show

 

"Other server" failed to perform the Cleaning up stale reference point because of backup being performed

and

cryptographic services failed while processing the onidentity(), this occurs during backups.

 

 

Thin provisioned HDD, load of space on both.

 

Just reinstalling the AV incase thats doing something it shouldnt.

I'd also make sure you have the latest or newer patch installed too. For example all my 2016 servers (physical and virtual) have the May 2017 update installed.

Lets me on C drive fine but the data drive is giving some grief.

 

Booting up a new sever on another host just incase.

Believe its fairly up to date, will check when i get back, gotta go out for an hour. Not going to touch anything incase it goes wrong before i go.

Update:

seem like it was the AV, uninstalled and it seems to be working like a dream again.

 

Will reinstall later, going to see if i can use the av only rather than the full suite.

 

Thanks for all the suggestions!
