    Problem with backend login

    I have an older (4.0.2.1) umbraco site that has a periodic problem where the users suddently can not login to the backend.  Restarting the w3svc service seems to solve the problem.

    There seems to be a connection to these events being logged on the server:

    Does anybody know what causes this and how to fix it ?

    Thanks

    Hi Mikael

    Does the umbracoLog table contain some entries as well?

    Hi Mikael

    Sorry for my late reply - did you manage to solve the issue?

    I'm afraid I have no clue about what the error could be, but I'm thinking if you have made some kind of customization to the instance recently? In example made a custom user control, xslt extension or something like that?
