Sounds like something DCOM permissions related, no idea why it would
work in 5.0 and not 5.5, have you got a restrictive set of permissions
in place at all? Some articles I read recommended running:

gpupdate /force

to refresh the loal groups and policies from the Active Directory but
it would be strange if that was your problem. Possibly the
installation of services has changed in Tomcat to effect the
credentials used to install the service somehow?
