Configuration is - 22 Mac Nodes 1 NEC SilentWriter PostScript printer 2 AppleTalk ImageWriter Printers ~ 2000 ft of 22 gauge phone wire, all nodes using PhoneNet or similar network connectors. One or two nodes on the net will lose sight of the printer at times. Often, unplugging a machine from the backbone truck will cause another machine to lose contact w/ the printer. Outage occurs through the network, with no rhyme or reason. Right now, the machine closest to the printer (next to it, in fact) cannot find the plasted thing! Help. 1) Does anyone have any familiarity with sich problems 2) What network analysis tools can you recommend for such a problem? Any hardware/software analysis products would be welcome. I have Seer & NetCheck. OI also have a copy of MacEcho from Simtel20, but it refuses to run. Any help w/ this program would be appreciated also. Thanks for any & all help. Mail or post replies, but be aware that this system seems to have some problems receiving mail (or has in the past.) -- Bill Douglass, TCADA "I dreamed I was to take a test, in a Dairy Queen, on another planet."
