Windows 7: Can't see NAS or XP machines on Network (64 bit RC)

15 May 2009   #1

Can't see NAS or XP machines on Network (64 bit RC)

So I have a network with 3 computers, a readynas, and multiple network printers.

Two machines have 64 bit RC 1, one has XP.

XP machine can see both Seven machines, and NAS.

64 bit machine one can see everything as well.

64 bit machine two could see everything when I did the first install of RC. I reinstalled to fix some boot manager issues, and now it cannot see the XP machine, nor the NAS from windows explorer. I can connect to the readynas through it's IP address in a browser no problem, I have full internet and networking between it and the first 64 bit machine.

No homegroup is set up on either seven machine. The network is set to Home. Drivers are installed for the ethernet properly, latest drivers.

I looked through settings and everything seems to be gravy. What am I missing. Nothing changed between the two installs except 18 hours of time. =/

Windows 7 64Bit RC (Dual Boot with XP)

It is funny... My networking was working fine on 7 (64 Bit RC).
Then all of a sudden... It is one way now.. The 7 PC can see all XP PCs etc and access their shared folders.
The XP machines can no longer access any shared folder on the 7 PC. Have not changed any firewall settings. Using the 7 firewall.

Self resolved problem I guess, after two or three reboots it's finally seeing all my network goodies.

Windows 7 64Bit RC (Dual Boot with XP)

My issue was on account of Symantec End Point Protections, broken implementation of Firewall on 64 Bit systems. uninstalled it. Did a custom reinstall de-selecting Firewall. Earlier, even though the firewall was not active, it had some files installed in the background causing this issue.

Windows 7 Ultimate, Signature Edition 64bit

I'm in that same boat. 3 machines: one netbook with xp, one xp mediacenter edition 2003ish, and my main machine with windows 7RC 64bit.

With the 7000 beta I could not see the xp machines from my 7 but could navigate there by ip address. Same for the XP machines, could see each other but not 7 and could navigate by ip.

Now with W7RC I cannot navigate to or from my 7 machine.
Also, I can not navigate to my router's settings log on screen.

windows 7 HP 64bit

Ive had no end of trouble with my network disappearing over the past few months. Tired 5-6 different builds and all had the same result.
I narrowed it down to Eset V4's firewall. Im not much good with firewalls so couldnt figure out what was stopping things getting through but after turning this off and using the Windows 7 built in one i have no more network issues.
