I often run into people in the CRM field who are very good at one or two things, they might be great programmers or a fantastic trainer. However, one of the skills I believe my customers appreciate that I bring to them is not the extreme depth in a certain field but a very good knowledge of many areas all concerning CRM. This ranges from subject as varied as management Consulting to nitty gritty network fixing, or just troubleshooting why that Outlook client won’t work as it should.
And it is in troubleshooting that I think that the breadth of knowledge often does you most value as it helps me to back off from the problem and view it from a different perspective. I also believe that despite the fact that you might have a fancy business card, you should get your hands really dirty to understand what is really going on and what the people are the programmers or technicians are talking about.
And the most important thing about troubleshooting, make sure you have friends, you can never know it all, but with enough friends, there are no limits to what you can know and fix! The best way to get a friend help you in troubleshooting is to help them of course.
I have recently been working a lot with networking and trying to configure RRAS which we use at our lab Environment and I struck a wall and used the Power of social media to ask if there was anyone around that could lend a hand. Thankfully there was, my friend Pete McCollough came back and we met up at a cafe and after some collaborative troubleshooting we found the error and Pete said a wise word that I will remember and would like to share, that being
– Networking is not very complex, but extremely specific
Which he had to explain to me of course as I am only a half-wit. What he meant was that compared to for instance programming Networking is not in its architecture very complex, however, not two systems are identical and usually every component has some part that has been manually configured which turns the troubleshooting hard by trying to find your way around an unknown maze.
In this case I had simply forgotten that our hosting partner had a firewall that blocked 443 and 80 why no traffic got through. I had check the other Three firewalls that the traffic passed about 15 times, but that didn’t matter. I so wished I had a debugger that worked for network traffic.
I was also informed that the following blog ranks this blog among the top 50 CRM blogs in the World which of course is very honouring. Maybe I am not a half-wit after all or maybe just lucky.

Running Microsofts CRM Demo VPC (Available on Partnersource) on Windows 7 is a bit problematic but can be done. I found a good blog that showed how it can be done using VirtualBox but there were some extra things that needed to be done to make it work.
As many of you probably are aware, from Windows Server 2008, only 64 bit versions of the server operating systems are available which isn’t very strange since the 32 bit versions of Windows only support up to 3.5 GB of memory which is really enough for even a small server.
Hence the Virtual Machine that Microsoft have released with a demo environment of CRM 2011 is based on this 64 bit environment. Since Windows Virtual PC, the Virtualization Technology for Windows 7 does not support 64 bit guest operating systems, it has been created on Hyper-V and is meant to be run on this virtualization technology. However, this is not really what you average CRM salesperson is running in his or her Lenovo X11 for many obvious reasons, power management probably being one of the most striking.
So, it is it just not possible to run the demo environment on a Windows 7 machine? Yes, it is. On the blog Leon’s CRM Musings there is a very informative posting on how to make the virtual harddrive work in the VirtualBox virtualization technology. I was quite amazed when I saw this working as this is quite similar to installing an operating system on a computer, ripping out the harddrive and screwing it into a completely different computer and hoping it will work. However, the Hyper-V virtualization and VirtualBox virtualization must be very similar from the guest operating system perspective, otherwise the operatingsystem would have given a lot of errors.
Do note the part in the posting that the demo image does not support being run as a SATA drive but must be run as an IDE harddrive.
There are some comments that both SharePoint and CRM are installed on port 80. This is in part true, but they are installed on different websites separated by different host headers.
However, the sharepoint site did not work when I tried running it, hence the document manangement from CRM did not work either. After checking the IIS website bindings and the host-file (C:system32driversetchosts) I noticed that the host headers for the SharePoint site and some other sites were pointed at the IP 188.8.131.52 and a quick check with ipconfig showed that this was not the ip of the current computer. Hence I just changed the mapping to be 127.0.0.1 (always means “this” computer).
I then closed all IE-windows, flushed the DNS (ipconfig /flushdns) just to be sure, then tried the sharepoint site, and it worked. As did the document management in CRM.
I saw some people in Leon’s blog commenting on the networking issues of making the exchange server communicate with the CRM-server. This can be done be setting the networkadapter in VirtualBox to “Internal Network” on the Exchange machine and using two adapters on the CRM machine, one with NAT (external) and one internal using the “Internal Network”. Both the internal networks adapaters need to be configured manually, but the external one can have a dynamic IP. If anyone doesn’t know how, please leave a comment and I will tell you how.
Regarding optimization of speed I strongly recommend upgrading your computers memory to at least 8 GB so that you can give the virtual machine between 4-6 GB. Try to give it even multiples of 512 MB as that will make for better memory management.
Another well known fact regarding VPC:s is disk access. It is highly recommended that you use a separate disc on a high speed controller (i.e. USB 3.0/eSATA/internal SATA).
As for processor power, it is not as essential, eventhough it is always nice. Try to allocate at least 2 cores to it. One for the SQL-server and one for IIS/GUI.
The recommendation that Leon gives to reduce the memory for the SQL server I am not so sure that is a good idea as CRM is very SQL heavy due to its meta data driven nature. However, if you only have 4 GB:s of memory and you have to make this VPC work, then you might have to try it. Kingston memory modules are very cheap now, 2×4 GB for a T410 is less than €100 last time I checked.
I have several computers, my “sales computer” is a Lenovo T410s Corei5 8Gb with 2 SSD HD. I use one of the harddrive for my host operating system and one for the virtual machines. I have removed the DVD-drive since I never use it, and the extra drive is a lot better use of the space.
Last of all, cudos to Leon for a great solution with VirtualBox for the VPC!
An additional thing to do is to convert the VHD to the Virtualbox native VDI-format for virtual harddrive using the media Media manager in VirtualBox. This is probably a more optimized format for Virtualbox and hence a bit Quicker. (I have not tested it, it is just a thought)
I have also tried to run the VPC on an external USB SSD, both USB 2.0 and USB 3.0 with 2 GB of RAM with 2 Cores on my Core i5 with the converted disk and it works fine. The SSD gives it a lot of extra speed.
