I have a customer that is upgrading a Unity server from 2.4.5 to 2.4.6. Just a software upgrade. He has converted the server from Win NT 4 to Win2k, with SP1 and high encryption pack. He also has applied SP4 for Exchange 5.5 and pretty much has followed the upgrade proceedure to the end. He starts the Unity upgrade and enters the necessary information including the LDAP port. The installation reaches a point where it stops the Unity services, and shortly after that a message comes up: Installation proceedure is not complete. You should re-run setup in it's entirety.<br><br>I suggested that he make sure he is logged in properly with the required rights. This is a stand-alone unity with no other nodes in the domain. The Unity is a Domain Controller and he is logged in as Administrator. Administrator is a member of domain controllers and should have all the necessary rights. <br><br>What may be causing this error? Does Unity create a error log? Nothing helpful was in the Event Viewer. This server does have plenty of memory (512MB RAM).<br><br>Any suggestions to where to look next? <br>Thanks in advance.<br><br>Jeff Schlesser<br>CSE<br>TAC Engineer<br>408-527-4204
