We have received reports of customers loosing Internet connectivity after installing MS08-037 (951748 and 951746).  This issue can occur on both the server and the clients.  This issue may occur when customers are running ZoneAlarm or Check Point Endpoint Security (previously named Check Point Integrity).  Our investigation so far has shown that no other customers are affected by this issue.

    We had this problem with someone running Symantec Endpoint Security.  We had to uninstall KNB951748, KB951746, and KB950159.  Does anyone know if there's an update to the update?

    I also ran into this and had to remove the updates to get ipsec to run. The effected server had neither zone alarm or checkpoint installed. Any word on when the updates will be updated?

    After installing KB951748 on our domain controllers, Apple OS X 10.5 client machines are having difficulties logging in/binding to the domain.

    We are running Filezilla server on Win XP Pro, and have been getting continual '425 Cannot open data connection' messages when a 'List' command is sent from the client.  AllTel customer support says they have been 'inundated' with calls, and they pointed us to KB951746.  Uninstalling it seems to be working.

    .. ok guys i have been having this prob as well .. i will follow the blogs and un-istall these updates. we have a network using SBS 2003 sp1 .. with clients running vista and xp sp2.. both clients have been affected. We also employ Symantec Endpoint Protection Manager and Client (v11.0.2010.25) A temp fix was done by assigning each of the affected users a static IP address. I will uninstall the updates and post the results. Thanks once again guys.
