Have a Win7 machine on a Win2003 Server and have to relogon every morning. This morning I had to restart the whole thing.
Welcome to window7forum,
Does the networking get fine after you reboot/relogon ? There may be a networking setting within your virtual pc software that you need to adjust. Just for example, MS virtual pc > networking > specify a folder to share > checkbox "Always share this folder" (or share it just this session) etc.
Do you have the adapter set to your physical network card (not internal or NAT) on the Win7 virtual machine?
No idea where to begin to look for this.
Could be related to the problem with XP where the network discovery needs some utility installed on the Win 2003 machine to work with the Win 7 network discovery. I will have to look up the exact phrase, LLTD I believe. I do not know if this is necessary in Win 2003 server, but you might check.
Network Map in Windows Vista does not display computers that are running Windows XP
If not that, have you tried modifying some of the settings in Network and Sharing? Do you show the network as Public or Private..?
In the networking options of your virtualization software.
KevinSpy:
Have a look at your power settings on the Windows 7 machine.
Open device manager
Expand network adapters
Select and then right click the adapter you are using for the problem connection and choose properties
Select the power management tab and uncheck the box that says something like Allow computer to turn off this device to save power.
Also you are going to have to investigate any power saving options in the control panel power applet that may be impacting the connection overnight, like sleep, hibernate, turn off this or that. Networking is about high availability and doesn't perform up to expectations when power saving schemes interfere
Would it have anything to do with the Windows Firewall and security?
