Title: HTTP Error 503. The service is unavailable.
Post by: C2A2 on 17 Jan 2019 05:15:38 AM
Hello,
I have installed CA 11.0.11 on WS 2012R2 (IIS8.5) and followed steps provided by IBM in below link to configure IIS.
https://www.ibm.com/support/knowledgecenter/en/SSEP7J_11.0.0/com.ibm.swg.ba.cognos.inst_cr_winux.doc/t_gateway_iis.html#gateway_iis

When I access cognos connection via IIS I get "Service Unavailable, HTTP Error 503. The service is unavailable." Error and Cognos application in IIS stops. In windows event viewer I get below error.
The Module DLL C:\Windows\system32\inetsrv\rewrite.dll failed to load.  The data is the error.
I have repaired and reinstalled "IIS URL Rewrite Module 2 (rewrite.dll)" multiple times but the problem still exist.
All suggestions are welcome :-)

Thanks

After you repair have you tried to restart the AppPool??? or restart IIS?
