I am trying to upgrade my Exchange 2000 server to Exchange 2003 and am running into multiple issue while trying to uninstall the IM service. I did not disable the ability to send IM's through the users profiles (Exchange Tasks) before I tired to uninstall the IM Services from Exchange. Here is a snipette of the log file, specifically the section where the uninstall errors out. == Begin Snipette == [20:39:38] No Parent Component specified for this Account in the ctor - defaulting the initial user value to empty string [20:39:44] Setting PTAdministratorAccount from custom property to ROADANDRAIL\Administrator [20:39:44] Setup configuration information: [20:39:44] This is a(n) Standard version of Microsoft Exchange 2000 [20:39:44] This is not an evaluation copy of Microsoft Exchange 2000; it will not expire [20:39:44] InstallSourceDir = Uninitialized [20:39:44] InstallDestDir = C:\Program Files\Exchsrvr [20:39:44] InetSrvDir = C:\WINNT\system32\inetsrv [20:39:44] System32Dir = C:\WINNT\system32 [20:39:44] LocalServer = MAILSERVER [20:39:44] SchemaMasterDC = FILESERVER [20:39:44] DC = FILESERVER [20:39:44] Domain = RoadandRail.com [20:39:44] DomainDN = /dc=com/dc=RoadandRail [20:39:44] NetBIOSDomain = ROADANDRAIL [20:39:44] NT5Site = Default-First-Site-Name [20:39:44] Org = Road and Rail Services Inc [20:39:44] LegacyOrg = Road and Rail Services Inc [20:39:44] AdminGroup = First Administrative Group [20:39:44] LegacyAdminGroup = First Administrative Group [20:39:44] AdminGroupContainingRoutingGroup = First Administrative Group [20:39:44] RoutingGroup = First Routing Group [20:39:44] 55ServiceAccountLogin = Uninitialized [20:39:44] PTAdministratorAccount = ROADANDRAIL\Administrator [20:39:44] This is not a clustered machine [20:39:44] Entering CAtomIM::ScInitializeExchangeAtomWithCtxInfo [20:39:44] Leaving CAtomIM::ScInitializeExchangeAtomWithCtxInfo [20:39:44] Entering CBaseComponent::ScPreSetup [20:39:44] The component "Microsoft Exchange Instant Messaging Service" is set to action "Remove".

Also, looking into the Event Manager, I see an error labeled "MSExchangeIM" with a catagory of NetworkLayer. Opening up this erorr, I see the following displayed: The network layer could not be initialized (Error 80040154). I have tried doing research on this error as well and came up with nothing. Any assistance would be greatly appreciated. I would prefer not having to Migrate my mailboxes because of the time it will take (16 hours). Thanks for the assistance. Charles Norman
