comment How to replace a fan on a 3com SuperStack 4500 unit (and where to find a fan)?
If one of you goes ahead and answers this, I will accept - I did not realize these used units were so cheap. Not even worth replacing the fan, I will just buy a used 'fully working' unit. I can even buy a bigger unit for around the same price!

comment OWA 2010 calendar is it possible to get the 2003 week view back or customize it?
I wonder if it's possible to modify the aspx or .js files? (though it would be nice to keep the stock view also)

Have tried light, no list view there. I just tried blind/low vision and it does not seem to have public folders (where the calendar is) and will not accept the url if I go directly.

comment why do I lose ping to a machine when using port mirroring / monitoring (sniffing)?
Only 1. Would the behavior I describe be considered normal? So in that case you use a second adapter?

comment 3com SuperStack 3, is it possible to replace a unit with a newer 'hp' equivalent unit?
Makes sense. I decided to not replace the unit, and instead remove the bad on, reducing the stack down to 4 units, which is still fine in my mind. I will replace it with a modern normal (non-stackable), but managed layer 3 poe switch, uplinked to the stack. This is the way we have been going in other closets anyway.

comment If you turn on spanning tree, how do you know there is an issue with your network?
I guess this is the obvious answer. I suppose I could use Splunk and feed it logs, and something like whats up to monitor the snmp traps and alert...

comment If you turn on spanning tree, how do you know there is an issue with your network?
The only problem is, that's not the answer to the question I asked. In my case, the network is WORKING. If spanning tree was OFF, and I had a network loop, it would stop working. With spanning tree ON, it theoretically would keep the network working, so how would I know that there is a problem loop for example, since the equipment would mask the issue? (the answer above about snmp/logs so far makes sense)

Maybe you could share at least the basic relevant entries for the second range?

comment vmware esxi 5, cant create snapshots and consolidate fails, how to delete old or consolidate redo logs?
Now when I try to consolidate snapshots, instead of failing right away with the 255 or more error, it runs for a while, then an error message shows failed because it could not allocate memory. Yet there is about 60% free (out of 16 gigs).

comment vmware esxi 5, cant create snapshots and consolidate fails, how to delete old or consolidate redo logs?
So I tried and it ran for a long time (hours). Near the end, it finally came up with an error "error caused by file [datastore1] myvm/myvm-000255.vmdk. So it failed cloning.

comment backuppc - how to backup remote (over the internet) clients?
Sorry, you are correct, I was answering the wrong question. I did however end up using crash plan, instead of backuppc for remote laptop type machines.

comment VMWare ESXi 5 unable to create snapshot - maximum file size
update: my backups were failing again, so I tried my 'consolidate' trick, and it's not working to fix it this time! Same error as described above. So I am still stuck, I am not sure why I am unable to create a snapshot of these 2 machines. 2 others on the same box are fine!

comment VMWare ESXi 5 unable to create snapshot - maximum file size
Its just under 3k (the vmx file) -- the vmdk is just over 8 gigs.

comment wireshark windows - how to remote capture/analyze from a tshark or similar install?
I guess that works for most of my use cases, but I am also hoping for a real-time capability. I wonder if for example I could use putty to create an ssh tunnel, or some other option?

comment Spanning Tree Protocol (STP) to prevent network loop back issues?
So it looks like it is enabled on my ports (see above where it shows "port protocol : enabled", but looks disabled in the device MSTP config. Even though it looks like it's on for the ports, does that mean it's NOT because it's disabled at the device level?

comment How to record SIP traffic / calls for future auditing?
I am really liking the oreka solution so far! It seems to work great, except that SOME of our phones are generating g729 traffic, some g711. The g711 work great and I see wav files, the g729 do not decode and stay as mcf files. I believe this means I need to either get the pay for version with the proper codec, or convert my phones to all stay on g711, which I am not sure if is possible or if there is a negative to doing that...?

Good Point. In our case, no PCI issues. However, we are legally liable for what is said on the phone and what actions are taken (or not), so recording is a necessity.
