kix32.exe shows as open file on domain controller

When I browse Shared Folders/Open Files on the domain controller, I see lots of users that have not released kix32.exe. About half of users in the office. Cannot figure out why. All users are running same OS (Windows 7) and same script - there is only one script for the entire office. THANKS

Re: kix32.exe shows as open file on domain controller

I've been doing a little eyeball research on this. It appears this is only happening with Window 7 64bit clients. I've seen the kix32.exe file listed in the open files on both Server 2003 DC, and Server 2008 DC, with kix32.exe versions 4.53 and 4.61.

Here are my results so far:

                  Server 2008  Server 2003
Windows 7 x64        Open         Open
Windows 7 x32         OK           OK
Windows Vista x64                  OK
Windows Vista x32
Windows XP x32        OK           OK

I have access to Vista x32 with Server 2003, but it will be a week or so before I can test it. If anyone has the other environments, please post your results.

Re: kix32.exe shows as open file on domain controller

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!!!!

Re: kix32.exe shows as open file on domain controller

A little more info. The kix32.exe process does not show up in the process list on the computer that is holding the file open on the server.

One office that I checked on the other day, had a number of kix32s open, but now has none. The only thing that has changed is the installation of SP1. Maybe its fixed now. I'll try to do some more confirmation myself, but if anyone else can confirm this, it would be helpful.

Re: kix32.exe shows as open file on domain controller

I found something new. On 2 DCs I disabled SMB2. Now no open kix32.exe where found. Can this a problem with sm2 function durable_handle? But I didn't find a Reg-Key to disable only this function.

I'm still seeing this problem too. I'm moving this thread to beta so it's more likely Ruud will see it.

Hi,

Has anyone tried any of the following Server 2008 hotfixes?

Re: kix32.exe shows as open file on domain controller

I've not applied any myself. I run a few server 2008 R2 boxes but for applications - not user access stuff and so far I'm not having any of these issues.

Re: kix32.exe shows as open file on domain controller

but it wasn't a w2k8R2 issue. it seems by the data given thus far that the problem is windows 7. and 64bit specifically.

Re: kix32.exe shows as open file on domain controller

Aha! No wonder I can't replicate this issue. The first thing I do at any client is set DelayedDesktopSwitchTimeout to zero on every system at build or deploy time.

I do it just because it is annoying as all getout!

Curious why this would fix it... this doesn't happen on 32bit clients... and only Win 7 x64...

I'm willing to give it a try to see though.

Well I only have a few and have not noticed the issue and I've not manually made the change either. Just haven't seen the issue yet.

Re: kix32.exe shows as open file on domain controller

Hi,

after more testing. I found that starting from our Netapp-Filer the problem was gone.
On the filer the option: cifs.smb2.durable_handle.enable was disabled.
After disabling smb2 on DCs kix32.exe also not opened.

From a german AD maillinglist i got the answer to test the following registry key:
HKLM\System\CCS\Services\LanmanServer\Parameters
Type: REG_DWORD
Name: DisableLeasing
Value: 1

After setting this key on all DCs tomorrow only 3 PCs ( from 300 ) holds kix32 open.

Re: kix32.exe shows as open file on domain controller

This is definitely not an intrinsic KiXtart issue. As apparently disabling SMB2 resolves the issue, it seems it is related to that.

I'll do some research to see if I can find any issues like this.

Re: kix32.exe shows as open file on domain controller

Just found a report in one of our databases that sounds suspiciously similar.
It is an SMB2-specific issue, and can leave file handles open indefinitely.

The issue is scheduled to be addressed in Windows 8.
