Al, It's happening on an AD/DNS Domain Controller, so no local admin on it. Ken http://www.MSExchange.org/ Is it a local admin on the machine? (I would assume so with those privs, but best to be sure). Al _____ http://www.MSExchange.org/ Hi Al, The account has the following rights: Account Operators Administration Domain Admin Domain Controllers Domain Users DNS Admin DNS update Proxy Enterprise Admin Enterprise User Exchange Admin Exchange Domain Servers Exchange Services MSNAdmin Mail Users MTS Trusted Impersonator Replicator RAS & IAS Services Schema Admin Server Operator. That is all ;) Is there anything that may need to be added? http://www.MSExchange.org/ What other rights does that account have that you are using? No we are in a single domain. The account is the Domain/exchange admin that I am using.... Where to next? http://www.MSExchange.org/ Do you have multiple domains? If so, where is the account located in respect to the installation domain? Yes it is a "user name could not be found" error. It is occurring just as the system is installing the services & modifying the registry. I have tried to find a record of it in the event viewer, and nothing was created in the log file, under security or applications. I have done a search for c00708ad on MS support and there is nothing, I widened the search to all of MS and still nothing. Went back to google and the same. Any ideas on which service the ADC may be using during the re-installation? Ken http://www.MSExchange.org/ Isn't that a "user name not found" error? Have you considered trying the readme file and the support.microsoft.com site vs. google? Al http://www.MSExchange.org/ Hello, I am just starting to get our system ready for adding in an E3K server, and when I am trying to upgrade the ADC to the 2003 version, I am receiving the following permission error: Win32 ID no: c00708ad error and the ADC installation fails. I am logged on with an account that ahs full Domain, and Exchange administration rights. I have done a google search and did not find anything. Can anyone suggest what else may need to be added to this account? Or what else may be causing this error? Thanks Ken ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------
