Can't browse yo my other PCs after a network change

[Guest]

History: I hav a home network setup with 5 or so computers. All are running
XP Pro with one laptop running VIsta Home. I have them all setup on the same
Workgroup and have always been able to browse around to the folders I have
shared with no trouble.

Cause: Last weekend my main router died so I replaced it. THe new router
used a different IP set then my old one so now everything has a new IP
address. Everything else is the same.

Problem: One of the PCs cannot browse to any of the others and none of them
can browse to it. I can go to DOS and ping the other PCs by name or by IP,
but when I try to do a \\name\share or \\IP\share to view it, I get the No
such PC error. Also when I go into the network neighborhood, entire network,
workgroup, it hangs for a long time and eventually comes back showing nothing.

I can't figure out what is causing this and am out of ideas. Can anyone
shed some light on this for me? Others have told me I'm screwed unless I
rebuild (which I don't want to do) but there has to be some sort of solution.

If you need more info, let me know.

Thanks!!

If the problem started directly from the router replacement, then the router is
filtering SMBs, between LAN ports.

You don't give the router make and model. Check the setup guide for either
"DMZ", "VLAN", or "isolation mode". This is a limited firewall between specific
router LAN ports.

The router is a Linksys WRT54G running DD-WRT (http://www.dd-wrt.com). The
part that is confusing me is that this only affects this one computer. All
the other ones can see each other just fine.

Also, none of these PCs are connected to the router directly. They go to an
8 port switch and all the PCs come off of that switch.

Is everything connected through the switch, and by Ethernet? What's different
about the problem computer?

Look first for a personal firewall or other security component that you had to
configure the subnet or another IP entry into.

Or look at logs from "browstat status", "ipconfig /all", "net config server",
and "net config workstation", from the problem computer, and from at least 2
others, and diagnose the problem. Read this article, and linked articles, and
follow instructions precisely (download browstat!):

Oh lord, do I feel dumb now. Just goes to show that even after 10 years of
Desktop Support, sometimes it's the stupdi things you just forget about.

I have Zone Alarm and have been using it for years. However I had my "Home
Network" area setup with my IP range of 192.168.123.1 - 254 since the 123 was
the settings that my original router used. Of course the new one uses
192.168.1.x so ZA wasn't happy about that. Just had to change the 123s to 1s
and now everything is happy.

But the Browstat page you have is what finally made the lightbulb go on in
my head.

Thanks!

YAY! It's Zone Alarm again!

Well, I wrote all of those articles, originally, for ME. So I could remember
all of the details. It was a strange day when I casually browsed into my
SiteMeter logs, and looked at "What are all those folks doing in MY website?".

So I'm glad that my articles were able to help you. Thanks for letting us know.
