Solved: intermittent server slowdown
Posted by Amy Babinchak on 25 June 2018 04:32 PM

At Third Tier we help IT Professionals solve problems big and small. When you need an extra set of eye or an extra set of hands remember that we're here for you. In this case we advised and the client did the work. We're happy to work either way. We can some or all of the work it is entirely up to you. We treat you like the IT professional you are.

Client: I have a WS2K12 R2 Server that every 3 to 6 months experiences a significant slow down. It usually lasts 36 to 72 hours and then all is normal again. I'm looking for someone to help me identify what is causing the slowdown so I can prevent or predict it in the future. This client has only one server, so it's the DC and handles DHCP and DNS. It does File and Print services and hosts two Windows 7 VMs via Hyper-V. It also hosts Sage 100 Contractor, Sage Paperless Construction, and Sage Estimating. Each of these Sage products runs a SQL Express instance. There are two backup programs installed: Retrospect for standard data and server backups and Altaro for VM backups.

Third Tier then asked a bunch of questions in one session try to narrow down the scope and reviewed the logs. We determined that the server was under warranty with Dell and that there had been a lot of firmware updates issued but not applied. 

Third Tier: Update iDRAC, PERC controller, NICs, Driver then firmware, Hard Drive firmware and BIOS. Always a good idea to keep the Dell OMSA up to date as well to easily show issues/alerts/logs of the server. Install a Time Server. w32tm /config /manualpeerlist:pool.ntp.org /syncfromflags:MANUAL. Meanwhile the client also modified the VM performance type. Run SFC scan and correct any corrupt files.
