Google allies with Verizon

This is a good partnership for both companies. The partnership was gone along ways for Google in getting the Android phones out there and Verizon has been growing steadily as it takes on AT&T. Bundling software is a slippery slope to a lot of legal issues as Microsoft found out though,

ASA rewriting DNS queries

This article was a god send for me. I was trouble shooting this issue for a while. In my case I had an internal device on a private vlan that needed to resolve the public address of another internal server on a different vlan but it would only resolve the private address.

I really hate when devices “try” to be helpful rather than just working they way they are supposed to.

UC500 Night Service with call blast group

I recently ran into a situation while setting up a UC500 Cisco phone system wherein the client wanted all inbound calls from the PSTN to ring on all phones. Ok, no problem, call blast group takes care of this. Now what was interesting is when they wanted to have a night service that forwarded to the Auto Attendant. Normally a call blast group will not trigger an extension specific event (call forward, etc) but I was pleased to discover that I was able to configure a night service extension and when turned on the UC500 bypassed the callblast and functioned properly.

So far I have been pretty pleased with the UC500 system as an affordable entry level phone system which competes very well with equivalent systems like the Mitel 3300CX.

Do you need to change where outlook stores it’s temporary files? Here is the reg key. I have had to do this with VDI implementations. This is redirecting to a share on a server called DC01.

%windir%\system32\REG.EXE ADD HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security /v OutlookSecureTempFolder /t REG_SZ /d \\dc01\Users\Outlook\Temp /f

Cisco phones not discovering Voice VLAN on HP Procurve switches

I encountered this issue and luckily I was able to find a blog entry about it:

http://mikemcarthur.net/article.php?story=20100602220125153

Essentially Cisco phones use CDP to discover their voice vlan. HP procurve phone’s use LLDP to accomplish the same goals. Now apparently this works fine with the Cisco 79XX model phones which are there Enterprise class phones.

However I was trying it with the Small Business line 500 series phones and it does not work. According to the article you need to manually disable CDP on the phones to make this work. The other alternative (which is what I did) is manually input the voice VLAN into the phone.

Hope this helps

XenDesktop 5 – A review



Posted by: Jason Tramer
Citrix, Desktop Director, Machine Creation Services, VDI, view, vmware, Xen, Xendesktop, XenDesktop 5

So as a consultant who holds both certifications with VMware and Citrix and working for a company which specializes in Virtualization I often find myself being asked, so which is better XenDesktop or View for VDI. The answer of course seems to depend on the time and date you are being asked. Virtual Desktop Infrastructure or VDI seems to be the hot new buzzword on every one’s lips.  VMWare and Citrix seemed to be locked in a metaphorical arms race for VDI where each is in a constant state of adding to their offering.

The newest offering from Citrix is their XenDesktop version 5. Having  implemented version 4 let me first talk about where I felt the deficiencies there and then I will go over which of them has been fixed.

XenDesktop 4

1) The install takes way to long and is way to complex

2) Overly complex architecture with too many moving pieces, particularly with Provisioning server

3) Standard images do not leverage built in virtualization snapshot technologies like View does for ease of use

4) Updating standard images takes too long and usually represents down time for users

5) Difficult to manage, not enough tools to quickly diagnose and resolve issues

So that’s the bad, now here is the good thing, XenDesktop 5 addresses all of these issues.

XenDesktop 5

1) Simplified install, including express option for POC’s and smaller implementations

2) Machine Creation Services now as part of the DDC, eliminating the need for Provisioning Server in smaller or simplified cases.

3) Machine Creation services leverages snapshot technologies for easy deployment of standard images

4) Updating standard images can completed with three clicks and has minimal impact on users

5) Desktop Director is a great new tool for managing the environment and quickly diagnosing and resolving issues.

Conclusion: Citrix did some great work with XenDesktop 5.  XenDesktop was already a powerful and flexible product but by adding simplicity and manageability they have greatly improved their offering to the VDI space.

XenApp 6 ““An error occurred while making the requested connection”



Posted by: Jason Tramer
20000, An error occurred while making the requested connection, hotfixes, IMA, licensing, qfarm /load, XenApp 6

Here is the issue. Xenapp 6 you are unable to launch any app, you get the error “An error occurred while making the requested connection”. If you run a qfarm /load command from CLI you get a result of 20000. There can be several causes for this but more often that not it is related to licensing.

Make sure your citrix licensing server is set up correctly and then go into your computer policies and make sure you have specified your licensing server, port, and edition correctly.

This issue is mentioned in citrix hotfixes XA600W2K8R2X64002, and XA600W2K8R2X64029, however after running these and rebooting my IMA service would not longer start on my server. Since this was a standalone installation I went back into the XenApp 6 setup and created and joined a new farm and configured it identically and problem solved so I would guess this is just a bug.

Group Policy scripts not being applied to XenApp sessions



Posted by: Jason Tramer

I encountered this issue a little while back and in hindsight in turned out to be pretty simple but it was driving me nuts at the time.

Here is the symptom, when a user opens a XenApp published application, the batch scripts that are pushed out using group policy don’t apply. The other symptom is that when launching the first app in a session also opens up published notepad.

Here is the real issue, and this only happens when you have notepad published. In the file associations in published notepad one of the options is .bat, so if you did a select all or accidentally select .bat as a file associations for published notepad it will launch your GP scripts in notepad rather than running them.

Redirecting folders in BES 5

I have been working with Blackberry Enterprise Server 5 for a while now, and I have to say I am still not sure I am loving the interface. It takes a while to find settings that used to be very easy for me to find.

One such setting was the ability to select which folders in a user’s mailbox gets synchronized. In BES 4 it was simple, you could just select the user and select folder redirection, but in 5 you have to hunt for it.

Once you select on a users name you will see a field called “Messaging configuration”, select “Default configuration” and then select the “Email” tab. From there go down to message redirection and select the radio box for Other folders and you can then select the folders for redirection.

Routing within an interface on a ASA and my triumphant return



Posted by: Jason Tramer
ASA, Cisco, intra site routing, routing, routing within a network

Well it has been a long time, but I am back! Sadly elements in my personal life have kept me focused on other matters for the last 8 months or so and I apologize for that but I am ready and eager to return.

For my first issue I want to talk about is with Cisco ASA’s and concerns how to set up a static route on an interface to point to another router for certain routes.

Let me give an example. You have your inside interface, lets say 192.168.1.0/24, and on this interface your have a router with an IP address of 192.168.1.10 which connects to a network of 10.0.0.0/24. Now you need your devices on the 192.168.1.0/24 network to get to the 10.0.0.0/24 network via 192.168.1.10 but that is not their default gateway. How do you do it?

Well obviously you could use static routes on the machines but that is bad practice. So you do it on the ASA.

You would set up your static route and NAT exempt as normal but it will not work. The ASA will be able to ping the 10.0.0.0 network but not the devices. Packet tracer will tell you that you have a Access List issue but you don’t.

You need to other commands to make this work:

same-security-traffic permit inter-interface
same-security-traffic permit intra-interface

This will allow your traffic to function as you intended
