HTTP 500 Internal Server Error / An error occurred on the server when processing the URL RRS feed

  • Question

  • I have just installed a copy UAG (source from MSDN includes Sp1, UAG 4.0.1752.1000 / TMG 7.0.9027.400) on a newly installed Physical Server running Windows 2008 R2 (fully patched from WindowsUpdate). I have only created a HTTPS Trunk using the local AD forest for authentication and when I attempt to logon to the Trunk (after I have entered the username and password) I get a HTTP 500 Internal Server Error. There has been no further customisation and changes to this configuration.

    IIs Log shows:

    2011-02-14 13:51:15 POST /InternalSite/Validate.asp |199|ASP_0173_:_80004005|Invalid_Path_Character 6001 - Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.1;+WOW64;+Trident/4.0;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+.NET4.0C;+InfoPath.3) 500 0 0 7

    I have also tried installing Service Pack 1 Rollup 1 hotfix package for Unified Access Gateway 2010 in a vain attempt to fix this problem but it has not helped.

    Has anyone got any ideas before I have to resort to reinstalling the whole server?

    Thanks in advance

  • I have found the cause of this issue. It is being caused due to the use of the colon ':' character in the Server Name of Authentication and Authorization Servers for Active Directory Server Type I created. Example, AD:domin.co.uk

    If certain characters are not permitted to be used in the Server Name, then they should be excluded in the validation code when creating an Authentication Server.

    I am not impressed having wasted days on this issue!
