SharePoint 2010 environment.
A little background information. Originally, this farm was stood up with FAST Search (though it was never properly configured). I unprovisioned FAST Search and opted for Enterprise search (for the time being).
I DisabledLoopBackCheck on all servers, I blew away the index, I verified my Default Access Account has full read permissions (and it can browse the sites with no issues).
I've created several crawl rules (FQDN and IP) to include complex URLS and the SSL cert (also tried using the DCA but then I get an error saying the site requires a certificate).
When I run a crawl (full or TL), I receive the following error message
"Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint repository, verify that the account you are using has "Full Read" permissions on the SharePoint Web Application being crawled. ( Error from SharePoint site: HttpStatusCode Unauthorized The request failed with HTTP status 401: Unauthorized. )"
I am not seeing anything in the application logs or SharePoint ULS. I've deleted the Enterprise Search Application and recreated to no avail.
2 DMZ WFEs
3 Trust servers (1 CAD, 1 Index, 1 APP)
Current Search topology is
ADMIN component on APP server
Query and Crawl on Index server.
I have tried to move the query component to the DMZ WFE but I get an error
"Topology activation was aborted because of Microsoft.Office.Server.Search.Administration.QueryComponentTransitionException: System.IO.IOException: The network path was not found."
Any assistance is greatly appreciated!
