I've had Win7 Ultimate (64-bit) running on a desktop system for about a year for all or at least most of that time, network discovery has neen a nightmare.
Bring up the browser and click on network and you then have to wiat 45 - 90 seconds for network discovery to list the machines on the network (this is a domain, not a workgroup).
Initially, it was that way *EVERY* time I opened a new browser. Eventually I found some registry hacks that at east allowed it to persist till the next reboot.
It is the *ONLY* machine on my network exhibiting this behavior; all others discover almost instantly.
If the problem ended there I'd probably just live with it, but this is also true in any program that has a file diaog.
I've been assuming that this is some sort of networking or AD problem. However, I believe I've now isolated a very unexpected culprit: VMWare Player.
I purchased a new laptop yesterday and upgraded it to Win 7 Ultimate 64-bit. It had no discovery issues.
I started installing various programs and utilities without incident.
After the VMWare Player install and reboot, the laptop began behaving *EXACTLY* as the desktop.
If I uninstall Player, the problem disappears; if I reinstall it returns.
Thanks in advance -
When I go into Control Panel and get to the Network and Sharing Center, I see two networks: my domain and an "Unidentified Network". The "Unidentified Network" has an access type of "No Access" and lists two Connections: VMWare Network Adapter VMNet1 andVMWare Network Adapter VMNet8.
I'm guessing that discovery is waiting for the "Unidentified Network" to return a list but because it has no access it is stuck waiting for a time-out.
Assuming I'm making a good guess here, is there any way around this?
Well, for better or for worse, here is my solution:
I disable both of the VMWare adapters and changed the network access on my VMs to NAT.
It resolved my discovery issues and I still have access to the network from the VMs.
If anyone else has a better idea, I'm all ears.
Hhmmm.. I don't know if there is a difference on 32-bit and 64-bit in Windows7, but maybe there is. I am currently using Win7 32-bit and have installed VMware player a week ago. So far, I haven't encountered any problem with my network. I am also using both laptop and desktop and both running in 32-bit. You might be getting the problem from its default settings I guess. or maybe sort of compatibility issues.
