We have an Exchange 5.5 SP 4 Windows NT 4.0 with SP 6a & SRP server that has been in service for years and successfully running Outlook Web Access. Last week one of them lost OWA functionality. Everything else seems fine. We discovered that the World Wide Web Publishing Service and the IIS Admin Service were stopped. We manually restarted the two services. OWA functionality was restored. BUT, in about 20 minutes the World Wide Web Publishing Service and the IIS Admin Service stopped again. This problem persists. We can not keep World Wide Web Publishing Service and the IIS Admin Services up and therefore OWA running for more than a few minutes.
We now have a SECOND and unrelated Exchange site with the SAME problem.
How do we keep these two services and OWA up?
