Error Code: 500 Internal Server Error. The target principal name is incorrect
Posted on 2006-03-19
After moving (i.e., an actual physical move to a brand new building) the Windows SBS server from one location to another, accessing OWA or Remote no longer work. Now this used to work (for several months). When I moved the SBS server, the only two things I changed were the WAN IP address and the Gateway address in the SonicWall (which is the external firewall we are also using with ISA 2004) because we rec’d new addresses. (BACKGROUND information on setup: using a Netopia router which the Sonicwall is connected to and have an SBS server (with the Blackberry server installed on it - but that is not causing this problem because it was working prior).
As mentioned, this used to work for several months so what would cause this “now” to not work? Creating the certificates and creating the publishing rules were actually done by someone else so I do not know how he did a lot of things. However, I have tried several things. In another forum someone suggested I re-run CEICW and I did but it still does not work. Could the certificate be looking for the old ip addresses? Can a certificate be modified? How do I delete the old certificate(s)? Do I have re-create it and if so, how?? I have checked the publishing rules in ISA and all show that certificate that he created and I do not see where it is looking for the old "static" IP address (I changed the static IP address in the Sonicwall for the WAN IP address). There is also a hosts file on C:\ and in that file, it shows the server internal IP address which that did not change.
Also for the CEICW, it states “create a web server certificate named “ISAcert.cer” in \sbcert folder and to also create an additional web server certificate named “sbscert.cer” and install this certificate in IIS. How is all of this done?
Since I am not even close to being an expert here, there’s a lot I do not know how to do but can definitely follow detailed instructions. So if anyone can just tell me what I need to look for, how to create certificates (or use the snap-in?) and anything else, I would truly appreciate it! I have been working on this for over 2 months now and if I was not confused at the beginning, I am definitely confused now! I have read and printed out so much information off of the internet about the “500 error message”, “publishing rules”, etc., that I do not know where to start anymore. PLEASE help!!!!!
