I cannot access the Internet after running Microsoft Update KB951748, what should I do?

Microsoft Update KB951748 is known to cause loss of Internet access for ZoneAlarm users on Windows XP/2000. Windows Vista users are not affected.


Sudden loss of Internet access.


Platforms Affected:
ZoneAlarm Free, ZoneAlarm Pro, ZoneAlarm AntiVirus, ZoneAlarm Anti-Spyware and ZoneAlarm Security Suite.


Microsoft and ZoneAlarm are aware of an issue that is affecting the ability of ZoneAlarm customers to access the Internet after the installation of the MS08-037 (KB951748) Security Update released on July 9th.


Both Microsoft and ZoneAlarm are actively working on the issue. For further help in resolving the issue, we suggest you contact ZoneAlarm customer service or visit the ZoneAlarm website*.


One of the temporary workarounds that is mentioned on the ZoneAlarm website is to change the ZoneAlarm Personal Firewall to a setting of “Medium”  protection. The ZoneAlarm site says that it does not recommend this option, as it may reduce your security level. Microsoft also does not recommend this workaround, but it may temporarily allow Internet access.
