To the assembled font of Retro-Wisdom: I've been searching the archives to see if there is an answer to my questions, but haven't hit upon one. I have multiple problems, but I think they all have to do with Win 2k (isn't Windows one of the more tenacious viruses?). I've got Retrospect 4.3 installed on a Beige G3/300 Mac with an ATTO UW SCSI card and an HP DDS-4 drive attached to that. OS version is 8.6, 192M RAM, with an Asante 10/100 Enet card. My first problem is that the system will crash when *comparing* Windows 2000 Professional systems. If I run a backup without compare, it runs 100% of the time. If I ask for verification, it will crash 100% of the time (but not on the same machine). I brought in my PowerBook (Pismo 400) to test with and I was able to backup & compare to a file (rather than tape) two of the problem systems without any trouble (ran out of disk space after 2 systems). So, I'm stumped on this, unless there's an issue with updating to 4.3 vs installing direct-though I can't see why. My other problem is that now the application can't see most of the clients (Configure-Clients-Network). After we cut over to a new switched network on 12/15, I couldn't see any Windows clients (either from the G3 or the PowerBook). I can see any and all Mac clients. When I returned on 12/22, I could see two of the Win Clients, both of which resided on Switch #1. Moving a machine from Switch #2 to #1 (restarting it after the move) didn't change the result for that system. The network looks like this currently: Linksys <--> Linksys EZXS16W 10/100 Switch (#1) <--> Win Client/Mac Client BEFR41 <--> Linksys EZXS16W 10/100 Switch (#2) <--> Win Client/Mac Client Router <--> Linksys EZXS55W 10/100 Switch <--> Win Client/Backup Mac The previous net config was something like: Linksys <--> 3com OfficeConnect 16 Port 10bT Hub <--> Win Client/Mac Client BEFR41 <--> Router <--> Linksys EZXS55W 10/100 Switch <--> Win Client/Mac Backup App The Windows machines are a mix of 95, 98, & 2k Pro. I've tried pinging each client machine-100% success. I've tried adding by address-100% failure (519). Prior to the cutover, I could see most, but not all, of the Windows systems. The two that didn't appear I used the the Registry edit hack to get them to show; those are two of the eight that don't appear. We are running DHCP, but I can't even see the clients in the discovery phase (when Retro uses a UDP multicast to find the clients). The one thing I haven't tried is uninstalling and re-installing the client, given the fact that they were working previously. Also, I keep hoping that if enough time goes by, all the clients will magically reappear (two showed up later on 12/15, after I had left). Right now I've exhausted my knowledge as well as the specialized knowledge of friends & colleagues in both the Windows and network space. If anyone has any suggestions, I'd be more than happy to try them out. I hope everyone has had a good Christmas (if that's your persuasion). Thanks in advance for your ideas.
