Operation could not be completed (Error 0x00000057) when adding new printer (driver)

This error occured after I messed around with printer drivers – perhaps I deleted a little bit too much in the registry. Whatever – it was not possible to add a HP Universal Printer Driver to the PC. I always ended up with the errormessage mentioned above. I had no problems installing other printer drivers.

I’ll make it short:
I ended up in renaming the following files in %systemroot%\system32\driverstore:

  • infcache.1
  • infpub.dat
  • infstor.dat
  • infstrng.dat

Before I was able to rename these files I had to take Ownership of these files. I really don’t know if it was a good idea to rename the files but afterwards it was possible to install the Printer Driver and the system is still up and running. And… I had to reinstall other printer drivers too.

So if anyone has more info about these files… let me know.

TS Web Access no icons visible

A very strange behavior occured the last days. A customer is using Windows Server 2008 with TS Web Access and TS Gateway enabled. When he tried to access his TS Web Access site he was asked for the password and then nothing happend. The browser was loading the website and after one or two minutes the TS Web Access site showed up with no icons for the applications in it.

It was possible to workaround that problem be running ‘iisreset’ but only for maybe 30 minutes and after a while it didn’t help at all.
I created a test site to check whether the problem was IIS related – but it wasn’t. The testsite showed up in not time.
Connecting to the server with TS Gateway Services worked without any problems.

I checked the TS Web Access Configuration on the server just to find that the same behavior occured there, too.

Time to open a case with Microsoft.

Meanwhile I sniffed a littlebit around with Procmon to see if there was anything special. I could see that the WMI-service took a lot of time to read the shell32.dll from an UNC-path. The enlightenment came when MS-Support told me that the icons for the applications in TS Web Access are enumerated by the WMI-service. The support asked me to check this registry key:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList\Applications

Within this regkey all published application are listed and the have a string value called “IconPath” – this was pointing to an UNC-Path instead of a local path.

After changing that path to a localpath (e.g. %systemdrive%\…) the problem went away.

HP Data Protector Backup slow (on HP Servers)

Well, there might be a few hundred reasons why the Backup is slow. But if you’ve tried everything else you might want to check this setting:

Or check this article (even it is from CA):

Saved me 5h of backup.

ArcServe15 SCSI-Error (on HP servers)

ArcServe15 ran into a SCSI error after backing up some GB. I got these error messages in the ArcServe Log:

E3719  Unable to write to media. (MEDIA=TESTTAPE [S/N: ], EC=Hardware Error)
E6304  Unexpected SCSI Sense Code[ABSL:3040 CMD<WRITE> SC:28h 40]

I checked the drive with HP LTT and wrote a few hundred GB on the tape without getting any errors. All other tests passed, too.

CA support sent me the following article which finally solved the problem:

https://support.ca.com/irj/portal/anonymous/kbtech?docid=478936&searchID#properties

Or check the picture (put the SCSI Information agent from the left side to the right side):

Backup runs like hell now.

BTW: Disabling the HP Management SCSI Information Agent also speed up the Data Protector on an other customers site.

Slow Mousepointer in VMware Console on Windows 2008 (R2)

Bad mouse “performance” can be caused by the wrong mouse driver. The mouse driver should be “VMware Pointing Device”. It seems like the VMware mouse driver is installed on the VM but not used. I had to manually change the mouse driver in all cases I had so far.

The driver can be found in the VMware Tools directory
%program files%\Vmware\VMWare Tools\Drivers\mouse

Little Update:
Another problem for the slow performance might also be the wrong driver for the Video Adapter. Even after installing VMware Tools the driver was “Standard VGA”. I changed that to “VMware SVGA 3D Driver” (Found in %program files%\Common Files\Vmware\drivers\wddm_video) rebooted the server and everything went totally smooth.

ArcServe 15 “Database Operations Fails”

I installed ArcServe15 on a new W2k8R2 server today. Within the setup process I defined the backup user “arcserve” that has Domain-Admin rights. After finishing the installation I tried to format a tape but it failed with the errormessage:

Device <2> failed
Database operation fails

While checking the SQL Express Permissions I found out that the “arcserve” User was not listed in the logins of the database. But the user belongs to the group “Builtin\administrators” Anyway I added the “arcserve” user to the logins and the error went away.

ArcServe is installed on a Domain Controller maybe it has something todo with that. I didn’t have the time for further investigation.

Citrix Merchandising Server 2.0 VMware OVA

I tried to deploy the new Merchandising Server 2.0 Virtual Appliance for VMware today. The “Deploy OVF Template” process started but after reaching 99% the deployment aborted with an errormessage

Failed to deploy OVF package: The request was aborted: The request
was canceled.

I downloaded the Appliance once more but it did not solve the problem.

To solve this problem I extracted the .ovf and the .vmdk files from the .ova file using WinRar.

I was able to import the appliance then by chosing the .ovf file I extracted before.
