HTTP Error 500.19 - Internal Server Error
Error Code 0x8007007e
Occasionally, while installing Land Explorer on Windows Server 2012 R2, users might receive an error message:
Potential Cause: WSUS and XPress compression
If this error is occurring when connecting to your Land Explorer, especially after setting up a new Windows Server 2012 (e.g. by IIS), it is possible that SafeGuard Enterprise Server: IIS 7.x / 8.x HTTP Error 500.19 in combination with Windows Server Update Services (WSUS).
This issue is because of the XPress compression schema module (suscomp.dll) which gets installed with WSUS. Compression schemes are defined globally and try to load in every Application Pool. It will result in this error when the 64bit version of suscomp.dll attempts to load in an Application Pool which is running in 32bit mode [enable32BitAppOnWin64]. 32bit mode is needed for SafeGuard Enterprise Server to run.
workaround: 1. Navigate to config.cfg 2. Create a backup copy of the file config.cfg and save it to a different location. 3. Open the config.cfg with notepad editor. 4. Search for the following entry:
<scheme name="xpress" doStaticCompression="false" doDynamicCompression="true" dll="C:\Windows\system32\inetsrv\suscomp.dll" staticCompressionLevel="10" dynamicCompressionLevel="0" />
5. Remove this entry.
Potential Cause: WSUS
Check with your Windows Server administrator to ensure that WSUS is properly installed. ASP.NET and .NET Framework 3.5 are required to run Land Explorer.
Potential Cause: Default Web Site connection
If the default connection to IIS website was set as "Application user (pass-through authentication), or the specificed user credentials expired, update the user credentials would solve the issue.
