We have a remote office that connects via LAN to LAN VPN to our main hq where our E-mail Server resides. The remote location has a 2008 Domain Controller. Our HQ has both a 2008 and 2003 DC. Our Exchange server is 2003 on Windows Server 2003. We have one particular client that keeps receiving Outlook pop-ups through out the day saying that connectivity to the Exchange server was lost and will be restored. These pop-ups are logged in the Application Event View as Event ID 25. This workstation also has been logging MrxSmb Event ID 3019 warnings in the System Event View.
Any ideas on how to resolve this would be greatly appreciated.
