P

As always over time scripts get updated and evolve – bring a bit of a powershell novice my scripts could probably do with a great deal of evolution but here’s version 2 of the script I posted previously I imagine this will only really be interestng to me but I thoguht I’d post it anyway – no ones forcing you to read! (if someone is forcing you to read leave a comment and...

Powershell – Check ICA response, Check for exiestence of file and uptime of multiple remote servers

P

Following on my previous post I spent some time today refining our ability to check the ICA listener across the farm and created a little powershell script that I thought I’d share. It probably wont be much use to anyone else as it only does a few fairly specific checks but here it is. It’s by no means perfect but does what I need it to Script will: 1. output servers that do not...

The importance of encryption – Web Interface

T

The following is an extract from a document I wrote a while ago which was written to try and highlight the importance of encryption: I’ve played with this type of thing before but it I believe Firesheep, although it may be used with questionable motives, has highlighted to the world quite well the importance of securing your web traffic by creating an exploit packaged so that it can be used...

Issue: XenApp 5 on Windows 2003 – ICA listener ‘down’

I

An issue I encountered when working with one of our customers today. The customer reported that users intermittently received a ‘Protocol Driver Error’ when launching applications from their XenApp 5 (windows 2003) farm. As you know Protocol Driver error is one of those brilliant errors of a million causes but essentially it’s the client telling you “I couldn’t contact the server using the...

Ardbp32.bin Load Balancing – HTTP

A

Thought it was time for an update – This is something I’d previously written when implementing Provisioning Services 5.6 sp1 and XenServer 5.6 FP1 into a a reasonable sized Presentation Server 4.5 farm that wanted to move away from their currrent physical servers to embrace the wonders of virtualization. It’s been said before but load balancing TFTP is difficult, and as...

XenClient RC2

X

As expected I’ve ignored this blog for a substantial amount of time – so much time in fact that my last post was awaiting a public beta of XenClient and since two release candidates have been released. I have finally managed to obtain a copy of XenClient and eventually a laptop that it will run on. I was quite disappointed after discovering my HP 6930p had an ATI graphics card in so...

Citrix XenClient

C

Well I’ve been waiting a while for this, you can call me sad if you like but really you’ll just be talking to computer as you read this… who’s sad now? XenClient RC is released. If I didn’t have to use my laptop tomorrow this would be going on my 6930p right now but unfortunately it’ll have to wait till Friday. For those people who have lives XenClient is a type 1...

WordPress: Publishing code containing quotation marks

W

Well in the interest of the blog I’ve just learnt something new when trying to publish the last entry. When trying to publish a code exert I noticed that the code would not display as text even when the <code> tags were used, apparently this is due to the existence of quotation marks within the code I was trying to publish. Thanks to Lorelle@Blogherald.com The answer was to use character...

Access Gateway Advanced: AlwaysUseClientLessURL

A

This is an old issue that I dealt with a few years ago that needed digging up a couple of weeks ago during an AGA install. It’s issues like these that caused me to start this log as finding the exact entry to add to the web.config file took me a good hour of digging through my sent items when I coudl have had them nicely detailed here! Issue: If SAClient fails to load when logging into CAG...
