Hi Guys, Sometimes upon boot all tray icons load, with the exception of ZoneAlarm. Taking a look at my "Event Viewer" the failure of ZA's icon, is preceded by, or the sequence of errors just before ZA are: DCOM got error "This service cannot be started... the next error The DHCP client service depends on NetBT failed to start... next error Timeout waiting for Webroot Spy Sweeper engine... next error The Webroot Spy Sweeper engine failed... next error True Vector Internet Monitor depends on vsdatant service failed to start Okay! I have (long time ago) "disable Net Bios over TCP/IP was told to do this to avoid malware. Not exactly sure why I'm mentioning it here. Could it be possible that the DCOM error sets up the failure of ZA, and ultimately the hang? Note this occurs only sometimes, requiring turning off the machine (no control, to shutdown) then re-boot & all is well. This is a standalone desktop running XPSP2, with a dsl connection & NAT router. Has anyone tried or used the following: http://www.grc.com/freeware/dcom.htm Grc says DCOM is not needed, and can allow malware. I think I tried this a few years back & had no internet. Also is "DCOM Server Process Launcher" service, the same DCOM grc.com is talking about disabling? If so why would TweakHound recommend leaving this service in automatic? I guess i'm rambling, but if anyone has run the DCOM thing from GRC with DSL & no problems, I would try it hoping to eliminate my occasional hangs & ZA failure.
