Hi,
Suddenly we started getting HTTP Error 503. The service is unavailable for a IIS 7 Production Website.
1. Website only works when Application Pool Identity is set to "Network Services" but didnot work when set as custom identity
2. Local User which which is used as custom identity , is member of IIS_IUSRS group and also member of Administrator group.
3. IIS_IUSRS and Custom Identity user have Read access to the web directory and Administrator have full access.
I am almost sure its is permission/privilege issue of IIS_IUSRs group but cant find what is missing and where ? Plesae help.
