I have been having problems with a Novell Netware server freezing intermittently. I have not yet been able to discern a pattern -- there don't seem to be any large print jobs, nor large data transfers going on. The server is an AST Premium 286, running Advanced Netware 286 v2.0a. The only thing that I can do is to re-boot the server. By the way, does anyone know how to recover the disk space that I lose when this happens? When I re-boot, the server says Sector XXX marked by FAT in use with no file, or something like that. It's not alot of space, but it is bothersome. Thanks for any help, Dan benderly@cs.columbia.edu

I had the same problem on two other machines... the problem appears to be a bug in 2.0a when using certain ethernet cards... Both servers that had this problem were using 3COM Etherlink Plus cards (3c505 I beleive) and when we replaced it with a standard Etherlink (3c501) card the problem disappeared (along with the throughput)... neither Novell or our dealer would ever acknowledge the problem... but when we upgraded one of our servers to 2.12 we put the Etherlink Plus card back in AND IT WORKED... for a non-existant bug they did a good job of fixing it!!! If your not using 3COM cards I'd be interested in what you were using??? Joe Applegate - japplega@csm9a.colorado.edu

We had the same problem with AST/286 server and Etherlink Plus. It ran OK at 8 MHZ but froze intermittently at higher speeds. We have gone to using NP600s in servers with very good results.

Dan:
First of all, what topology are you using?
I used to experience this problem (at the company I work for in NYC).
The problem resulted from poor and worn network cables. A few feet of cable
was sitting near the heater pipes and a few connectors were loose. The freeze
ups stopped after we replaced ALL of the wires with new ones. Troublesome, but
bet method in the long run.
If you wish, you may call my office in NYC and ask for Tony in the Tech. Dept.
and tell him Johnny sent you. Micro Computer Systems - (212) 247-0420.
