Userenv Error 1058 - Windows cannot access the file gpt.ini

I had an issue on a Domain Controller where we would get the Userenv error 1058 in the application log everyday, the DC showed no faults, replication was working and it was more of an annoyance that the log was not clean rather than an error to get resolved.

I downloaded the Windows 2003 Support Tools and then checked with a DCDIAG and NETDIAG and both passed correctly and this confirmed my thoughts that the DC was working as normal.

I had a search on this issue and found that the problem can be caused by the Distributed File System cache and that using the dfsutil tool you can clean this up.

I ran the command dfsutil /PurgeMupCache and this cleaned out the cache, I then ran a gpudate /force and then Group Policy processed successfully and the error was gone.

-3948 VCB API Exception - vSphere DR

i had a issue where my vSphere Data Recovery backups would not start, each time they displayed the error -3948 VCB API Exception. Not exactly a clear error message to go at.

I then noted that I had made changes to my internal DNS and the internal DNS server the appliance was using we no longer in service and this error is really a DNS server to say I cannot find any host names for the ESXi Servers.

I changed the DNS in the appliance via the console and then the update allowed the backups to start correctly.

Upgrade IOS on Cisco 2960 Switch

Just a quick note on the new upgrade process for the 2960 range of switches.


Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:

Switch# archive download-sw /overwrite /reload
tftp:[[//location]/directory]/image-name.tar
The /overwrite option overwrites the software image in flash memory with the downloaded one.

The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.

The /allow-feature-upgrade option allows installation of an image with a different feature set (for example, upgrade from the IP base image to the IP services image).

For //location, specify the IP address of the TFTP server.

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:

Switch# archive download-sw /overwrite
tftp://198.30.20.19/c3750-ipservices-tar.122-50.SE.tar
You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.

Blackberry Express Server Web Console will not load after Maintenance Update 5.02

If you are intending to deploy the BES Express Server Maintenance Update 5.02 to your BES Server 5.01 then make sure you do so as the BESADMIN user. If you install the update as any other user the update will install correctly but you will find that the Blackberry Administration Service Console will not load and Internet Explorer will display "Page cannot be displayed".

I suffered this myself preferring to make installations with a specific Domain Administrator account and found that my console was no longer functioning. After much searching on Blackberry Support and finding others in the same situation via Google a colleague suggested he had found that Blackberry updates should always be installed as the BESADMIN user.

It is not really how the idea of security groups should work but it will save you no end of head scratching if you make sure you use the BESADMIN account, if you have already installed as another user just re apply as BESADMIN and the issue will be resolved.
