[OPLINTECH] GCPL: Public computers losing internet connection

[Mann, James H.]

Thanks Josh
Although we cloned the computers they all have unique names i.e. X-pub01 and static IPs so staff can turn off Websense.
We considered MAC address conflicts because we reused the static IPs so we put them on DHCP over night and that didn't correct the problem.
In theory a bad switch port would have demonstrated the same problem on the old PC same with the cat 5 cable.
A great mystery...and I hate it when the problem is random.

There is a variety of things I'd check in such a scenario, most of em you probably already have...

Make sure you don't have a switch somewhere that is flaking out.
IP conflicts, if you're using DHCP try hard setting some IPs to see if that fixes it. If they're already hard set, make sure there aren't any duplicates.
Check your license for your PC management software to be sure you haven't exceeded its limit. ( it sounds silly, but I ran into this once and "weird" things began to happen)
Computer names, if you use a cloning software like GHOST, check for duplicate computer names on the network. I'm guilty of that mistake too.

Good luck. :)

We have recently upgraded 70 public computers.
The new computers are randomly and sporadically losing connection to the PCReservation management stations and either displaying a message asking for a library card and PIN or station unavailable. When the error occurs the PC will also not connect to the Internet until it is restarted.
These are identical Dell 740, XPpro, IE and FireFox, Microsoft Steady State, latest PCReservation and LPTOne.
We have:
Uninstalled SP3
Installed Microsoft updates
Turned off Automatic updates

What is making this frustrating is that it is not all the computers and never the same computer that exhibits this behavior.
I accept the fact that it may be in Steady State but thought I'd post here in addition to a couple other lists.

Any and all suggestions are welcome.

TIA
