Error 1128 - An attempt was made to load a program with an incorrect format - group policy error

-

hello,

i hope well.

we have 150 provisioned servers run same image.  each day anywhere 2-5 of them come lot of 1128 errors in event log.  running group policy results shows error message, "an attempt made load program incorrect format"

the actual policy can vary , include 1 or more of following:  citrix group policy, group policy drive mappings, group policy internet settings, group policy registry, internet explorer zonemapping.

once event happens reproducible running gpudate.  have compared server next bad server running gpudate @ same time, hitting same domain controller , 1 works works , 1 doesn't doesn't. 

comparing "hklm\software\microsoft\windows nt\current version\winlogon\gpextensions"  doesn't show differences between 1 works , 1 doesn't.

bouncing server fix problem @ least short term.

any idea on how fix once , all?

thanks

hello,

as issue randomly happened on different computers, seems network related issue. please analysis gpsvc log more details.

and reboot several times, issue may disappear. and if user connects network on slow link cached credentials, group policy may not processed. please try disable slow link follow link below:
