We have a stand alone 2003 Exchnage server thats open for OWA over SSL. I jhave configured the server but we have a problem that If users click the logoff button they get a "page cannot be displayed error" or "The connection was reset error". The only way to correct this for them is to restart IIS and they can login again... I have looked all over the web for a solution and found nothing. I have checked the SSL cert and all seems to be ok. We are using a self cert. At times the OWA does drop offline but retarting IIS does sort this out. The server has the latest updates installed and exchange has been service packed. Would it benifit me to update IIS to version 7 as its currently on 6b or would I hit more problems?
