    OWA down

    Another Exchange question while we're on the subject.

    We run Exchange 2003 on our PDC. Occasionally webmail becomes inaccessible, normally when the server's been up for more than a week... Is there any way i can restart/enable it (by services or otherwise) without rebooting the server?

    This may be a sympton of something deeper, dunno. Ideas please lads (oh, and ladies)

    Sounds like it could be your IIS WWW Publishing Service that has a problem. I would create a .bat file with the following lines:

    net stop W3SVC
    net start W3SVC

    Save it somewhere on your c:\ and then create a scheduled task to run it every night at 4am.

    EDIT:/ of course you can and should test this first by waiting for the OWA problem to occur and then opening a command prompt and typing net stop w3svc <return> and then net start w3svc <return> and see whether it is working again.

    I would also suggest looking in the event log for errors, specifically relating to IIS etc because you should be able to resolve this without resorting to the .bat file above. The .bat should only be considered a temporary fix.

    Thanks for that dude. It's happening just now (web access dead) but the restarting of w3svc didn't resolve it i'm afraid

    You getting any error messages? Can clients get to their mailbox using another client?

    Mostly all is well - they can get in using the full Outlook client program. Web access both internally and externally is dead.

    Trawling through logs atm...

    While you are checking that out, try restarting the exchange virtual server i.e. HTTP protocol in System Manager.

    Try doing iisreset - this will restart the iisadmin service as well which might help.

    So are the clients getting usual 'Page cannot be displayed' gumph or are you actually getting a useful error message?

    Firefox says: The connection was reset

    IE (through ISA 2006) says: The page or file cannot be displayed
    Reason:
    The connection to the specified web server has been lost.
    Technical error details:

    Error Code 502 Proxy Error: The specified network name is no longer available.

    DNS issue? Have you checked for any conflicting ip addresses? Does the same server also handle DNS / DHCP?

    Theres no other servers in the domain also handling DNS? Just wondering about replication delays. At one point i was having real issues with AD replication when my predecessor set up a second DC. Ballsed it up, reformatted and started again without demoting the server. Just deleted the server from AD. It was only when we got exchange and had problems with connections dropping, services stalling, etc. that we found hidden away in the schema a reference to the previous instance of the DC. Once this was deleted exchange has run like a dream.

    Check disk space and mailbox store, We had an exchange box that would start falling over if it approached the mailbox store limit. First OWA would break, then IMAP then the MAPI
