We have the same problem since months. The problem is with Startup-/Logon-Scripts from GPO and Logon-Script for Users.

For our students we habe about 300 Win7-64vit PCs, which only use the Startup-Script ( cmd ) which started a KIX-Script. Every mornning we have some PCs which have kix32 opened every time, and othe PCs chaning each day.

But its not a KIXtart-Problem. It must be something like timing or so.

For testing I create a special Script:

%0\..\EVENTC /T success /SO poolstest /ID 99 /L application /D "pingtesta" > nul:
ping 127.0.0.1 -n 2 -w 1000 > nul
%0\..\pingtest.exe 127.0.0.1 -n 18 -w 1000> nul
%0\..\EVENTC /T success /SO poolstest /ID 99 /L application /D "pingteste" > nul:

eventc is a copy of eventcreate; pingtest.exe a copy of Win7-ping.exe.

With pingtest you got a sleep/wait time of n seconds.

If n gt 15 or so all the 300 pcs has testping opened. Between 1 an 10 seconds only a few pcs has kix32 opend.

I looked for settings and special GPOs but unitl now; no solution.

For a workaround I changed the startup-script:

\\naf2.uni-trier.de\domaincomputers\netlogon\kix32.exe \\naf2.uni-trier.de\domaincomputers\netlogon\updates\pools.kix

And now only one pc has the trouble !!!!!

NAF2 is not a windows server; is a Netapp-Filer!!!!
