500 Internal Server Error in ISA One of the most difficult errors to troubleshoot when using ISA or TMG is the 500 Internal Server Error. It’s so difficult because it is one of the most generic responses yet it has a number of possible causes. We’ll look at a few of the most common ones in this post, along with what to do to verify the cause and fix the problem. Look closely at the response message to see what supporting details are in place, and consider https://support.microsoft.com/en-us/kb/841664 what is going on between the client and the ISA/TMG or between your ISA/TMG and the internal server. Are certificates in use? Check the ISA/TMG logs to see if you find: “A certification chain processed correctly, but one of the CA certificates is not trusted by the policy provider. 0x800b0112 (-2146762478)” in the logs. If there are certificates in use, check the ISA/TMG server’s certificate store to http://www.chicagotech.net/msapps/isa3.htm make sure that the root certificate authority and any intermediate certificate authority are trusted. This includes both the certificates securing HTTPS communications and any client certificates used to authenticate the user. Importing the root and intermediate CA certificates into the ISA/TMG server’s operating system store if they are not already present will resolve most certificate issues. If you are unable to do this immediately, use HTTP to communicate to the internal server and a different form of authentication for the client. Not supported? When the client makes a request that is not supported by the ISA/TMG, or the response from the destination server is not supported, the ISA/TMG may return “Error Code: 500 Internal Server Error. The request is not supported. (50)” to the client. Often, this is caused when a client request doesn’t specify content encoding but the published server responds with a content-encoding specified in the HTTP response header. This is most likely to happen when compression filters are disabled on the ISA/TMG. To fix this for client proxy situations, follow the steps inKB927263. For secure publishing, set the SendAcceptEncodingHeader property using the VBScript found on this MSDN article. Target principal name is incorrect I have only

However after i tried all recommendations and possible solutions, i still have the problem.1 ISA 2K4 std with 4 NIC. The external NIC has about 40 public IP adresses. The Exchange 2k3 server is on the internal LAN.The OWA sites are on the Exchange server and they have different internal IP adresses. They have different isa server error certs obtained from the internal Cert authority.I exported the certs and imported them on the ISA as described in an article published by Thomas Shinder. Any ideas? All three OWA sites behave in the same way although they have different certs. The ISA2k4 is a member of the domain. I also tried to edit the hosts file on the ISA. e.g.:172.26.113.84 webmail.internal.net. the web listener on the ISA uses these certs.
