Unable to login to Citrix server via RDP or ICA

We have recently set up some new Windows Server 2008 R2/Citrix XenApp 6.0 servers.  For some reason, users could not launch a remote desktop to them even though we (thought) allowed this.  Turns out there is a policy which blocks this by default.  I found the answer here: Re: Unable to login using RDP or… Continue reading Unable to login to Citrix server via RDP or ICA

A fatal error occurred while trying to sysprep the machine.

Today, while getting ready to deploy an updated Citrix farm for a set of Line of Business applications, I got an error during the sysprep process.  The machine in question is a 2008 64 bit machine.  It has Citrix and all the applications installed.  It is also a Hyper-V VM.  I created an answer file… Continue reading A fatal error occurred while trying to sysprep the machine.

“netvsc” error in Hyper-V guest

We use Citrix Presentation Server for a number of applications, and lately we have had a significant increase in issues with one set of our Citrix servers.  We have 3 main sets of Citrix servers and the problems have only been happening on one set.  One of the sets doesn’t have this error, but wouldn’t… Continue reading “netvsc” error in Hyper-V guest

An online pack already exists…

Situation:  I have a 32bit file server running Windows Server 2003.  I have a new 2008 R2 (x64) file server running on Hyper-V.  Did I mention that the R2 server is on Clustered hosts?

DPM does not remove expired recovery points

I have been using DPM for about 7 months now.  (I tested with it for a few months before that.)  I never installed 2006, but 2007 seems to be working ok.  I have a few complaints, but I have complaints about all the backup software that I have ever used.  None of it really makes… Continue reading DPM does not remove expired recovery points

New Features in System Center Virtual Machine Manager 2008 R2

Of the new features coming in the R2 versions of Windows Server 2008 and SCVMM, I think these two are the obvious winners: Support for Live Migration: With Windows 2008 R2 adding support for Live migration, it’s now added as a new migration option in VMM R2. Live migration requires the source and destination host… Continue reading New Features in System Center Virtual Machine Manager 2008 R2

Replica disk threshold exceeded, or Recovery Point Volume threshold exceeded

Great! :(  Now what? Well, if you have a new DPM server and not a lot of protection groups created, and you haven’t been protecting anything much, you can just click on the link in the warning message that says “Allocate more disk space for replica…”  That pulls up a pretty window that looks like… Continue reading Replica disk threshold exceeded, or Recovery Point Volume threshold exceeded

The right way and the wrong way to disable the the firewall…

I use Server 2008 for a lot of things these days and I tend to not use the Windows firewall for most applications.  Here is an interesting note for the right and wrong way to disable the firewall and why doing things “the way we have always done them” isn’t always the right way: Although… Continue reading The right way and the wrong way to disable the the firewall…
