eSafe license expires

I just received the following interesting question:

What happens if our eSafe license expires?……Because it expires this weekend!!!!!!!!

Interesting question, because I never encountered such a situation. Normally the license is renewed in a timely fashion or a trial is stopped before the license expires. I searched the Knowledge Base from eSafe and found an article. This article tells the following:

Evaluation license: when an evaluation license expires, eSafe allows all traffic to pass through without any scanning at all.

Registered license: when a registered license expires, eSafe scans and blocks traffic, but stops receiving updates. Important note: if there are any licensed add-on’s installed (URL filter, Advanced Anti-Spam), they will stop functioning after the registered license expires.

Citrix Terminal Server License Server problem

One of our customers is using a Citrix NetScaler appliance for SSL VPN capabilities for remote users. I tried to start an application (RDP Client) through this SSL VPN solution, but I couldn’t succeed. I was able to login and I would see all the published applications, but when executing one, I received the following error message:

The remote session was disconnected because there are no Terminal Server License Servers available to provide a license. Please contact the server administrator.

So I did contact customers system engineers, because I thought the problem was related to the customers Terminal Server License Server environment. I thought this, because I was still able to use SSL VPN solutions from other customers. They couldn’t find any solution for my problem and that’s correct.

The solution for the problem is found on my own laptop. I stumbled upon this TechNet article. I opened my registry and deleted the following folder and subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing\Store\LICENSE000

This did the trick. I was able to execute the published applications again without any problem after rebooting my laptop.

HP ProCurve licenses

During an check-up on a network, I looked at the configuration of two HP ProCurve 5400zl switches. One of these switches functions as the core switch and default gateway for the various VLANs. To improve the availability and redundancy of the default gateway, I mentioned the configuration of VRRP (Virtual Router Redundancy Protocol).

On of the two core switches had the opportunity to enable VRRP with the command: router vrrp. The other core switch didn’t had the option to enable VRRP. I found this a bit strange, because both switches have the same hardware properties and firmware version. I spent some time looking at the HP Procure website.There I noticed that theHP ProCurve 5400zl switches require a Premium License to enable VRRP. I didn’t even knew that HP ProCurve switches had different kind of licenses, but after contacting the supplier and obtaining the license, I could enable VRRP and improve the availability of the network.
