Question

NAS multiple connections

Asked by: Dsmith2k7

My company is using a My World Book 1Tb NAS on its microsoft network.  The machines are a mix of XP and vista however the issues are occurring on the XP machines.  The error message happens after entering the password to access a folder and is shown in the code section below.

I have tried the following already so please read and don't suggest these:
1) Checked for connections to the resource using net use and there are none.  
2) Windows firewall isn't running.
3) No connections from other machines on the network
4) Used IP address to connect instead of resource name (didn't work)
5) Updated device firmware
6) Disabled Norton firewall

The problem is also intermittent which makes it more difficult to solve.  This seems to be an error message with several possible causes so I am willing to award points based on potential solutions offered (as long as they're reasonably insightful - no offense but it seems some people just answer a lot of questions really quickly without really reading them).

So have you tried a formal approach to debugging this problem?

I would suggest shutting down all the servers on the network, shutting down the NAS box and then bringing the NAS box up and getting it settled, then bring up the servers one-by-one to see if this gives you a repeatable error situation.

i notice on the web that in an earlier version of this device a maximum of 5 connections was supported.

I have to say this looks more like a device for the home than for the office - skimping on quality especially for a backup device can be counter-productive and costly.

Well just to explain a little more about the network setup we have - there are seven computers connected to a router with three printers and the NAS device.  There aren't any servers on the network.

As per your suggestion to use a systematic method I disconnected all the computers from the nas using net use * /delete and verified that no connections existed using net use.  I then tried to connect using the computer with the issue - it seems to only be one from my testing.  I was able to connect using the ip address of the device but not with its network name.  The ip address connection seems to work at all times.

The maximum of five connections concerns me however I did attempt to connect more than five times successfully, some of those connections where both ip and network name from the same computer though.  The reason for purchasing a product meant for home use was not an attempt to save money but rather to have a device which can be run by those with limited technical knowledge.

re ip address v name. Do you have a DNS server somewhere on your network? if yes then make sure all the servers and the NAS box are in it and that your 7 machines all use it. if not you need to create a definitive hosts file and make sure that all 7 machines are using it.

 

by: Dsmith2k7Posted on 2009-08-24 at 07:09:05ID: 25168424

Well as I said we don't have any servers on the network, this problem is pretty much resolved now as I have given every client a batch file for disconnecting all active connections to the nas.  

Its unfortunate imo that Microsoft has put this error message into its software as often even its own software will create a new connection (office) and deny users access to the drive through the os.  I think its an impractical security measure which does more harm than good but ah well.  

If anyone has a better suggestion than supplying batch files to everyone - i.e. a hack to turn this security feature off or  similar - please let me know.

I'll award connolly the points because systematically eliminating computers was helpful in solving the problem.
