Hi! Haven't had to ask you guys any questions in a long time! That's a good thing. Hopefully you can help with this issue as well as in the past....

Overview: I have connected a new wifi laptop and a new linksys router to my previously working network. Now I have 2 vista computers (one laptop wifi), and 2 xp computers and one printer on the network. Currently, they all connect to the internet (after lots and lots of stressful hours). But, for the most part, they do not see or talk to one another.

I say for the most part because each computer sees a different number of others on the network, and each can access different shared files.

I can give you exact specifics of which does what, just tell me what you need to know.

Give This tutorial by SpaceCowboy706 a read, it's got just about everything you'd need to know.

when you add computers to a network you've kind of got to make sure they all get setup the same

also...what's the main purpose of your "workgroup"? is it mainly for file and printer sharing?
you might want to think about getting a NAS (Network Attached Storage) system...it's basically a hard drive with a network card...though some of them (most of them now) are getting pretty fancy...you can set up authentication on the devices (to keep the kids out of the financial documents etc...) and they're pretty much plug and play...alot of them now are coming with built in print servers so you can attach printers to them and share them that way...with a NAS and/or a print server you don't have to worry about the "host" being on either....just leave the NAS on all the time and y ou're always connected...some of the fancier ones also allow you to access them easily from OUTSIDE (say you're at mom's house and you want to show her some pictures of the new stove but you forgot to bring them with....just connect to the NAS from outside through whateve rmethod it provides and you're good to go)

it's my opinion that the old fashioned windows workgroup (what you've got set up) is dead.

Hi, Thanks for the quick response.

I've been through the network setup tutorial. Before I added the wireless laptop and new router I was sharing correctly between all the computers. I'm wondering if there is a hardware problem with my router. Is there an easy way to determine that?

.....well...you could try with a different router if you've got one near by....though.....i would doubt that this is router related....it's probably more of a setting or something on one of the machines

More info, update:

2 machines (C1 and C2), 1 xp, 1 vista, can see and view shared folders on the other 2 machines (C3 and C4), also 1 xp, 1 vista.

The 2 machines than can view the others, C1 and C2, cannot be viewed at all by anyone. C1 and C2 are not seen as located on the network, in fact, even pinging to them fails.

All the machines are in the same workgroup and all have the same file sharing configurations. All machine have internet access.

Any ideas out there???????

check the firewalls on the c1 and c2 machines (windows firewall and any other firewalls)....do you have file and printer sharing allowed there? try completelly disabeling the windows firewall on those two machines and see if there's a difference

c1 is fixed, the xp unit. I checked the firewalls, but that didn't change anything. I use Macafee security center, and in there I was able to go into advanced security settings and enabled the ICMP, which allows the computer to be pinged. All other security levels stayed the same and the firewall is still on, but now I can accss C1 from all the other computers. ..... I tried the same exact thing on C2, but that didn't work - yet. This one's the vista and maybe I need to tweak the settings a bit more.

I'll report back when I find the final fix.

Been there done that - many times over! This machine was accessible on the network prior to installing the new router. I triple checked that network discovery was on with no password and turn on file sharing...... None of that has worked yet.

Since I was able to fix the xp by enabling ICMP, I'm thinking the problem might be somewhere within that area of internet security.
