Hi guys need some help here IIS died on me in a big way the other day and consequently the smtp service started crashing the iisadmin service. I have followed an ms article (dont have it handy) to remove and reinstall IIS and reinstall exchange, mount the old stores. All this seemed to be OK, the stores mount, the services start, OWA works, mail flows too and from the gateway etc. The only problem i have now is that when i try to view existing outlook profiles or create new ones, even for newly created ad users the names cant be resolved. I have checked DNS and network connectivity on the server and clients and all is well. If I fire up both event viewers (server and client) at the same time and try to open the profile or create a new one, after it outlook errors it doesn't log anything to the server or client events, which is helpful. The event logs on the server do not contain any errors at all pertaining to this or other. The only thing I haven't tried yet is to re install office, as I haven't got access to the cd yet. If any one has any tips or has come across this before I'm all ears Thanks Greg Mulholland
