Hi,

Weird one for you guys. One of our users has started to experience an anomaly where her Outlook 2007 shows a security alert whenever she opens the program. It is not affecting her usage and Outlook opens fine whether she says Yes or No to 'Do you want to proceed'.

The security alert is quite common in that it relates to autodiscover.domain.com and has the wording 'The name on the security certificate is invalid or does not match the name of the site'. When you click View Certificate though it references some unknown certificate called secure.prepaidcalls.net?

On an Exchange level, the only certificate in place is a self signed one and we have no other SSL certs. This problem is only being faced by a single user opening her Outlook on a Terminal Server.

Any help would be appreciated. Thanks. Please see the screenshot attached for more details.
