server has been in production since jan. 2012 no issues.

when attempting start service manually, presented with the error "windows not start active directory web services service on local computer.  error:1053: service did not respond start or control request in timely fashion."

upon inspection of error log, see following errors after start attempt:

timeout reached (90000 milliseconds) while waiting active directory web services service connect.

eventid 7000
active directory web services service failed start due following error: service did not respond start or control request in timely fashion.

there no log entries in application log, , there hasn’t been entry in \active directory web services log since end of last month. the last entry is:

eventid 1004

far can tell looking @ logs , checking ad , replication, dns, dfs, , else, systems seem working except adws.

have done following (in addition hours of searching , research):

added “<add key="debuglevel" value="info" />” , “<add key="debuglogfile" value="c:\adwslog\adws_trace_log.txt" />” microsoft.activedirectory.webservices.exe.config enable logging, service doesn’t seem logging anything.

have copied “microsoft.activedirectory.webservices.exe” file working server.

have export/imported registry keys working server.

attempted re-register adws dlls.

have uninstalled/reinstalled hotfixes installed prior point when service stopped.

after installed current updates system.
