If the Citrix Program Neighbourhood Agent is slow to connect to the PNAgent web service and then takes time to display a list of applications, it’s probably related to folder redirection of the Application Data folder. Program Neighbourhood Agent, by default, stores cache information in the following folder:

Outlook Web Access can be protected with an extra layer of authentication via RSA SecurID. This can be implemented in one of two ways:

Truly geeky people will appreciate the ability to run their mailbox on their very own Exchange cluster running on their laptop. Not quite high availability but high on a list of silly things to do. Here’s how to create a cluster in VMware Workstation:

I’ve just spent yesterday and today working on a site where the client had a need to run both the Microsoft Java VM and the Sun Java VM on their Terminal Servers. (The Microsoft Java VM is used for one site only, yes developers strike again). I was pretty happy when I was able to use Presentation Server 4.0 and Application Isolation Environments to get these to work on the same server, in Internet Explorer, at the same time. Here’s how:

Back in June, Microsoft created a resource section on TechNet for the Windows Firewall, check it out here. There is also a link to an article from way back in May 2004 about how Windows determines if the computer is on the domain network or another network and thus when to apply the Domain Windows Firewall profile or the Standard Windows Firewall profile settings pushed out via Group Policy.

We’ve been accepted into the Citrix Access Gateway 4.5, Standard and Advanced Editions Beta Program. No word on a NDA yet, but hopefully I might get a chance to post some details.
