RDP Stops Working After SP1 2008 R2

Leave a comment

I was finishing up my SP1 rollouts on server 2008 R2 when a couple employees were complaining they could no longer RDP into the servers. Brief check of the eventlog showed:

Message = Faulting application name: svchost.exe_TermService, version: 6.1.7600.16385, time stamp: 0x4a5bc3c1
Faulting module name: rdpcorekmts.dll, version: 6.1.7600.16952, time stamp: 0x4f1f9e66

Well that’s no good.

What I ended up doing was:
services.msc
remote desktop services – set this to automatic and change to always attempt to restart the service if a crash happened.

Is this the most correct way? Probably not, but it worked for me.

Error 800F0818 SP1 Install

Leave a comment

I was trying to upgrade a few 2008 R2 servers to SP1. Two of the three were successful without any issues. The third gave me some trouble – so I found a way to fix it.
Fast forward a couple more weeks and I upgraded a pair of identical 2008 R2’s to SP1. One success. One Failure. So now here’s my documentation (lot of help from http://jasonduffett.net/post/5189439239/windows-2008-r2-service-pack-1-error)

Download and run this file:

Open the log file:
C:\windows\logs\cbs\checksur.txt
Scroll to the bottom where it says “Unavailable repair files”
We want to know the servicing\packages\PACKAGENAME

Take ownership
takeown /f c:\windows\servicing\packages\PACKAGENAME.cat
takeown /f c:\windows\servicing\packages\PACKAGENAME.mum

Grant permissions
icacls c:\windows\servicing\packages\PACKAGENAME.cat /grant administrators:F
icacls c:\windows\servicing\packages\PACKAGENAME.mum /grant administrators:F

Copy from another system
copy \\anothersystem\c$\windows\servicing\packages\PACKAGENAME.cat "c:\windows\servicing\packages\"
copy \\anothersystem\c$\windows\servicing\packages\PACKAGENAME.mum "c:\windows\servicing\packages\"

Re-run the assessment installer tool.
Re-run the sp1 installation.
Profit

Samba Logging on Ubuntu

Leave a comment

Should work with debian also.
Ubuntu 10.04.4 LTS x32 system fully patched with LAMP, SSH, and Samba already installed
* Installed samba via the webmin interface

Install the local syslog server
apt-get install sysklogd

Edit the syslog server
nano /etc/syslog.conf

local7.* /var/log/samba/log.audit

Save and exit
touch /var/log/samba/log.audit
/etc/init.d/sysklogd restart

Edit Samba to enable the logging
nano /etc/samba/smb.conf

vfs objects = full_audit
full_audit:prefix = %u|%I|%m|%S
full_audit:success = mkdir rename unlink rmdir pwrite
full_audit:failure = none
full_audit:facility = LOCAL7
full_audit:priority = NOTICE

Save and Exit
/etc/init.d/smbd restart

You should now notice the file attempts at /var/log/samba/log.audit

Proxmox Mouse Not Working

Leave a comment

I was copying Windows-based machines from VMWare and Hyper-V to proxmox – only the mouse stopped working after I would finish copying. It would get “stuck” in the bottom right hand corner of the screen – I could right-click and get a menu option to pop up, but other than that it was completely useless.

Now I’m a big fan of the command line, but on my windows hosts it’s a ton easier to have mouse control.

So I found this guy’s blog:

VMWare mouse problems – mouse stuck in bottom right corner

Basically do the following:

Open Regedit
HKLM\System\CurrentControlSet\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}
Find the registry key “UpperFilters”
Remove the word msvmmouf – keep all other entries in there, but tidy up the spaces/returns if necessary
Under this 4D36E96F-E325-11CE-BFC1-08002BE10318 key, see if the other 01, 02, 03 etc folders have any mention of vmware. Delete the entire key if they do (example: highlight 02 and hit delete).
Reboot.
Profit.

I also had to remove a few vmware entries:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1001354

Delete the following:

HKEY_CLASSES_ROOT\Installer\Features\C2A6F2EFE6910124C940B2B12CF170FE
HKEY_CLASSES_ROOT\Installer\Products\C2A6F2EFE6910124C940B2B12CF170FE
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Features\C2A6F2EFE6910124C940B2B12CF170FE
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\C2A6F2EFE6910124C940B2B12CF170FE
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\C2A6F2EFE6910124C940B2B12CF170FE

HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.

I also got a Processr.sys issue (fix found here http://pve.proxmox.com/wiki/Processr.sys):
DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS
processr.sys

Edit the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm

Find the “Start” key

Change it from the default value (mine was 3) to a “4”

Show Version of Python

Leave a comment

I needed to know what version of python I was running, so I immediately tried:
python -v

No dice.

What does get me the version:
python
import sys
print sys.version

And then I noticed that as soon as I get into Python the version is displayed. Palmface.
