Hi, I originally posted the query below on another Microsoft site, but they suggested I should post here as "Your question is more complex than what is typically answered in the Microsoft Answers forums. It is better suited for the IT Pro audience on TechNet. Please post your question in the Technet Forum " Hope you can help! Thanks Alan C Hi. Im looking for some help on a problem which has had me baffled for a year or so now ever since I upgraded to Windows 7 (home premium version). Ill try to be brief but provide all the information that may be required to offer advice. I have a setup at home which consists of a desktop PC hard wired to a Belkin N+ router and a laptop which connect wirelessly to the internet via the router. The desktop and laptop both run Windows 7. I have setup a home network and it all works fine. HOWEVER, I also have a music server (Cambridge Audio 640H) which is basically a mini ITX type of PC which I believe runs a Windows CE type of operating system. Previously before I upgraded the desktop and laptop from XP to Windows 7, I had the music server hard wired to the Belkin router and could share music files between it and the desktop (basically to provide backup and play about with album art). The network configuration for the music server was basic it has an option to give the server a name (it has a factory default name of Azur), select DCHP (or not) and to give it an IP, submask and gateway. Also a password, although I think that it independent of the name. Since upgrading to Seven I have found it impossible to access the server, although ifI use the "cmd" prompt and ping "Azur", I get a successful ping - what it actually returns is ping Azur[192.168.2.15]. If I then typed 192.168.2.15 into the address bar, a windows username and password screen would come up, but whatever combination I tried, I could not access the music server and a message would appear Access denied client does not have access to the resources on the server Again, another however, since spending hours on the internet I eventually came up with a fix suggested for other folk who were having similar problem with NAS devices, which was a registry edit change of creating a new DWORD for LMcompatibilityLevel. This was really way beyond my experience level, but I tried it and now if I type Azur in the address bar I get access via my desktop PC, but it is limited the music containing folder (called media) appears, and if I click on it the hundred or so sub folders (abba, beatles, rolling stones etc etc) appear but none of them will open. Previously I could drill down to an individual track and play it. From what I have picked up by researching the problem it appears that there is a successful workaround for other versions of Windows Seven involving changing some security access options, but this facility is not available in the Home version. I apologise if Ive gone into too much detail, but wanted to try and explain the problem as best I could. Any advice would be much appreciated. Thanks

1. Have you contacted Azur Technical Support to find out if this hardware and software are compatible with Windows 7? There is no listing for Azur in the Windows 7 Compatibility Center. 2. Have you tried following the Networking Guide for Windows Vista: http://www.cambridgeaudio.com/assets/documents/AP219701Azur640HNetworkingGuideWindowsVista.pdf 3. Have you tried the Vista Network Patch: http://www.cambridgeaudio.com/assets/documents/VistaNetworkPatch.zip You need to find out from Azur Technical Support exactly what you need to do to get this working with Windows 7. The vendors of third party hardware and software are solely responsible for supplying solutions to any problems you encounter interfacing their products with Windows 7!

Rick thanks for the reply. I havent contacted CA directly as one of their FAQs says Windows 7 is not currently tested with the 640H as the 640H was developed and tested 5 years prior to Windows 7 being released, so we are unable to say at this point whether the instructions for XP or Vista will be the same, or even if the 640H will work with Windows 7. The main reason that music servers are in decline and that we discontinued the 640H is that in the last couple of years, the platform for digital music has changed vastly away from servers and towards streaming devices such as Sonos and Logitech, and streaming services such as Spotify. The 640H is therefore no longer in production. As such, support and service will continue for the product, but there will not be further development or updates to the 640H Also - and more interesting - is another FAQ (mainly to do with Apple, but also MS) which I have enboldened the key parts The 640H is almost 5 years old now, and has not been tested with Apple O/S 10.5. As such, we cannot offer support for Mac beyond 10.4.x. The 640H was developed under the lifespan of Windows XP and Apple O/S 10.2 which we fully supported and continued to support throughout the life of Vista and 10.4. The 640H, as the existing networking guides specify, is a slave to the network. What this means is that there is no anti-virus, firewall or other such software in the 640H that restricts its network communications. It uses the standardised TCP/IP framework which both Apple and MS use as a low level basis for computer-to-computer communication. It is however, the higher level coding that Apple and MS employ in their operating systems to improve their security which restricts the 640H from connecting to a computer. Sharing folders within Windows is an example of such security. This is why some customers report that the computer can connect to the 640H, but the 640H cannot connect to the computer. It is because the computer itself that is blocking the 640H. Although we have tried to help customers as much as we can with the existing guides, it is in fact the operating systems themselves that the guides address and which require the most attention in solving these problems and not the 640H. The 640H is no longer in production, and with every product there comes a time when we can no longer offer technical fixes to complex problems as a result of what Apple and MS decide to do to their operating systems. However, trying to move on and solve my particular problem, yes I have looked at the networking guide and tried both static and dynamic to no avail. HOWEVER I had not been aware of the patch. While I do not know what it does, I suspect it may be something to do with the LMCompatabilityLevel registry change I mentioned in my original post. CA say Windows Vista uses a different authentication level by default (NTLMv2) to that of Windows XP and embedded servers such as the 640H (LM and NTLM). This means that a <st1:place>Vista</st1:place>machine cannot access the 640H without LM and NTLM protocols being enabled in <st1:place>Vista</st1:place>itself As a rough check, As I mentioned in my original post I had changed my LMCompatibilityLevel as per this link http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/network-share-not-working-through-windows-7-home/cc7adcd8-5380-4a48-89ed-bde1125c5f2f?page=3 (see post by Calu Home Tech) to a value of 1 and this had at least allowed me to see the music server, so I changed it to a value of 3 and tried to access the music server, I could not. So I then installed the CA patch, this restored my access to the music server but only partially as before. When I checked the LMCompatibilityLevel value it had been changed back to 1 - presumably by the CA patch. SDo, just to repeat what the problem still is if I type Azur in the address bar I can see and access the music server, but it is limited the music containing folder (called media) appears, and if I click on it the hundred or so sub folders (abba, beatles, rolling stones etc etc) appear but none of them will open. All that happens is that I get a scrolling green line in the adress bar and to all intent it freezes. Previously (on XP) I could drill down to an individual track and play it. There is obviously a communication problem of sorts, but it seems crazy that I can get halfway and then no further!! Any help would obviouls be appreciated. Thanks Alan C

I sympathize with you about your situation, but if Azur is not going to support the system with Windows 7 there is not much that can be done. I know that Microsoft is not going to publish a patch to Windows 7 just to accomodate one piece of hardware. Without support from the manufacturer of the hardware you are pretty much on your own to figure out a solution.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Rick, Sorry have to disagree - it's not a just an Azur problem, I spent ages on the net trying to find a solution and came across scores of post of others who were having similar issues - with NAS drives, other PC's etc. it's a Windows 7 additional sophistication problem as far as I'm concerned. Interestingly, and most tellingly as far as I'm concerned I seem to recall that a lot of the others who had problems, there was a tweak that could be done to some security level or other IF they had the next level up of Windows 7. If you had the basic "Home" version as I have, then the only option was the registry change, which worked in some cases and not other. Thanks for replying anyway.
