Office Standard 2010 Sale windows 7 - Win7 - Win

Hi all,Office Standard 2007,

I have not too long ago setup a Windows7 Greatest 64bit machine which I prepare on employing in choice to my aged windows xp machine to complete development on. Nevertheless I'm having difficulties connecting for the fileshares exposed from the Windows Server 2008 (SP2 not R2) 32bit server around the network.

I have trawled google but been unable to search out any remedies that operate up to now.

The error

"Login Failure, unidentified username or password". Password prompt keeps on appearing as clearly the authentication is failing in between the boxes.

What performs:
Connecting to shares around the Win2k8 machine through the XP box
Connecting to shares around the XP box in the Win7 box
Connecting by means of RDP to the XP box from the Win7 box
Connecting via RDP to the Win2k8 box from the win7 box
Connecting by way of RDP towards the Win2k8 box from your XP box
So I can suppose that a) I'm not obtaining any concerns with incorrectly typed passwords & b) there are no network connectivity issues between the machines.

What doesn't work
Connecting to any password protected shares on the Win2k8 machine from your Win7 machine. We have not tried non-password protected shares.
Connecting to the win7 box from the win2k8 machine.
Additionally I have tried a few suggestions floating round on the web, such as setting LmConnectivityLevel to '1' in the registry, and setting the Network Security: Lan manager authentication level in secpol.msc.

There have also been a few comments that the timezone/datetime need to be the same on both machines,Windows 7 Sale, they are,Microsoft Office Professional 2007 Key, even so there is one difference. The win7 box lists everything in "UTC" and the Win2k8 box lists everything in "GMT" (I'm based in London so this is expected).

Additional Info

The machines are running NOT on a domain, rather they all belong to the WORKGROUP workgroup.

I have tried both User and Administrator accounts around the Server all with the same result.

The usernames are always authenticated against users on the server,Office Standard 2010 Sale, so are entered in the form SERVER\UserName in the login prompt.

There are other non-windows 7 machines around the network so I cannot really go fiddling with the network settings too drastically on the 2k8 server, however it is essential that I can connect to your server from your windows7 machine.

Any help gratefully accepted.


Update 1.

I've mot fiddled with firewalls on any of the machines, my thinking behind this being that given that independently all the machines can communicate,Genuine Microsoft Office 2010,Microsoft Office 2010 Standard Key Windows 2008 Hosting Windows Server 2008 We, and filesharing performs amongst the win7 <-> xp box <-> server, just not among server <-> win7. I will try turning off all the firewalls to remove them from consideration though.
