Server 5.5 not accepting new connections

[Baloo]

We have three servers running FMS 5.5 v.1; two are G4s running OS 9.2.2 and one is a PC running Win2K server. Max Users is set to 50. Clients are on both Win2K and/or OS 9.2. This set-up has been running relatively smoothly for years.

This morning the two Mac servers suddenly stopped accepting new connections (with less than 50 users logged in). They could be pinged and users who were logged in at the time didn

All three servers were physically moved to the new room but only the two Mac servers are experiencing the problem? Did the IP/subnet change with the move?

[Baloo]

the IP's, subnet mask, and domains are all the same

Baloo:

If the software all seems unchanged, then the only clear change is network hardware (even if it is only cabling.) Have the hardware checked out.

IT swears that the hardware is solid.

They are fine this morning, which makes me think it may be user related.

Edited to add:

The cabling (at least from the computers to the wall) is also the same. The computers were unplugged, carried across the street, and plugged back in.

IT would swear that it isn't a hardware problem.

The machines all respond to pings when FM server stops functioning. The applications continue to function and users who are logged in are still able to move about in records and make changes to the Databases. If it was a hardware problem or a cabling problem, I would expect to see more symptoms across the board of loss of network connectivity or machine functionality.

The network cables are new (and fresh out of plastic), the network patch panels are new. The switch which these machines collapse back to is new. And, of the fifty other devices which were moved into that same room, none of them are experiencing any network dropouts. And, these machines worked fine for a week after the move.

So, I'm not so inclined to think that it is hardware, but I'll give that some more consideration.

Hmm... I suggested a hardware problem because you indicated that the IPs, subnet, etc. were unchanged. Could IT have done anything to the software on the boxes when they were moved? Or, are you sure that FMS is in the foreground, with nothing else running on the servers? It's all very curious.

Can you run a packet sniffer on the server or client to see what's going on?

>>Could IT have done anything to the software on the boxes when they were moved? <<

That's part of the whole strangeness of it all. I was the guy who did the unplugging and plugging back in. It was purely a physical move. And, yeah, FMS is in the foreground. The machines are dedicated to running the server software.

I'll see about getting a sniffer in the chain and watch for something odd.

Thanks.
