    internal OWA error

    Since last wednesday, without any changes been made that I am aware of we keep this error message internally.

    Externally still works fine and so does staff using the full version of exchange.

    Its our server but the internet line comes through our LA with filtering ect.

    Are you thinking this could be an external issue?

    If it an internal server, you should really have an exclusion in place from your proxy settings - otherwise you're adding extra hops unnecessarily. That message is coming from your upsteam proxy - smooth5.kirkless.gov.uk (unless you name your internal proxy like that?).

    So, it looks to me like the upstream proxy is replying saying it has no idea what server that is - which would be right.

    The request is being sent to your LEA and not resolving up there (not unreasonably).

    Add a proxy exception or try the FQDN

    What does an nslookup give you? And have you checked your internal DNS servers to make sure there's an entry for it in there? How about connecting via the ip address rather than the name?

    getting no-where fast here.

    Update:

    some machines work some do not, even in the same GP.

    GP update has the same effect, not restricted to certain areas.

    But if it's an internal service, why are they involved?

    Indeed. If its hosted in-house, it should be routed directly from client machines to server without touching external servers at all - ie. it should bypass all proxies (eg. emley:81 should be an exclusion in internet options for the proxy).

    All our internal servers avoid our proxy entirely.

    Was an issue with one of there smoothwall servers we were told. Its an internal service however that is what caused it to break. I would look into the issue further but we have a new exchange install coming next week so we can get things set up correctly then on the new box.
