Hi I installed PG 2.0 (regged) on my XP Pro SP2 system yesterday. Fairly uneventful, the install went smoothly and PG began "learning" my apps. I added the 3 NOD32 executables to the allow list and things were going well. Then I woke up this morning and found my backup software (Dantz Retrospect 6.5) had failed. The way the backup software works is there is a "server" that has the tape drive and main backup software, and this communicates with a "client" daemon running on my machine which is the one with all the DiamondCS stuff on it. Pretty standard arrangement i think. Anyway, I got the following error message in the backup server's Log: "Trouble reading files, error -1010 (API request bad)" and "Can’t use Open File Backup – error 1017" /edit: I forgot to mention, the PG Log shows no blocked attempts, or anything (plus it is in "learn mode" still anyway.) Additionally, I began getting the following error in my Event Log: "The Computer Browser service terminated with the following error: This operation returned because the timeout period expired. " This happens after a few minutes of starting the Computer Browser service, it dies again. I can manually start it again, but it will die in a few minutes again, which makes it impossible to browse network shares on my LAN. I never had this before, and all I did yesterday was install Port Explorer, Process Guard and TDS-3 (all regged versions) so one of them may be causing this conflict. Any idears?
