comment Unknown device on network with strange ports open. Trying to find it
The thought that it is a wireless access point is one of the unspoken possibilities that worries me.

comment Server 2008 BSOD about once a week
The servers in my example above were R610s, but yes, an R710 has 3-channel memory.

comment Server 2008 BSOD about once a week
On a system with 3-channel memory, 18GB is probably three banks of 6G each (4G + 2G modules). My company has about a dozen servers with that exact configuration. Not an issue. We had a guy last year who though the same thing and reconfigured a few of them with 4x4G modules totaling 16GB, but of course that configuration drops down to 2-channel access and NUMA was all jacked up. Performance on those servers dropped by a third.

comment Is it safe to delete log file in C:\Windows\system32\LogFiles\Httperr
It may not be safe to delete them if your company has any sort of compliance requirements for retention of activity logs. Also, these can be a valuable source of forensic data in case of any hacking incident or investigation.

comment DB Server Disk I/O utilization
...or to improve the queries to reduce disk I/O. Sounds to me like a lot of full table scans. I say Indexes first, Spindles second.

comment Windows based rsync server
In our organization we primarily use DFS-R, but for our incremental offsite transaction log backups which have constraints on when they need to be transferred it's completely unacceptable because the complexities of the staging folders and lack of guarantees as to WHEN the files would be transferred meant that we were often experiencing backlogs and delays. The other case is for software releases where we need to update content across an entire set of web or application servers. They MUST be updated synchronously in our system. So for those two types of transfers, we use Rsync instead.

comment ESXi server reverted to installation defaults on reboot! How can this happen?
@mark-henderson This is actually my default assumption. What worries me is that they actively deny having done anything of the sort, and there appear to be no installation or other logs from which to prove it one way or the other. I much prefer to have an incompetent sysadmin making mistakes but who can learn from them and be trained, than having servers mysteriously resetting themselves.
