Peachtree 2010 networked with 2 workstations & 1 server. 1 work station running vista 2nd work station running xp home server is also running xp home This is NOT a new setup. It has been working fine for a few years, however, last login attempt resulted in error message "peachtree is unable to connect to its database". I need to resolve this issue.

get a usb2.0 lan print server and plug the usb 2.0 into printer and the blue ethernet cable into the print server.
here are a few examples
PM1115U2 bt startech or
TL-PS110U by tp link

why..
it will save you headaches
if the sharing p.c is off you have no way to print.
if you add a usb print server
you can print any time from any computer

if you want to share the printer on the other computer they must have matching work group names in the computer ID's.
then when adding printer select networked printer

1- Make sure that these services are running on both systems :
Computer Browser
Server
Workstation

2- Make sure that both PCs are configured to be on the same network IP address

3- Make sure that firewalls are not blocking the traffic bettween these 2 PCs

System restore on XP is restoring individual PC stations but because you have probably shared folders on linux server you have same problem on server. Solution:

• Remove network cable from linux server
• Install some antivirus solution for linux server (in case you don't have one) and scan and clean server from viruses.
• Also after you remove network cables from workstations scan and remove viruses from XP stations
• When you finish those steps atach network cables and probably you will not have that problem

Reason for that is becausesome viruses and trojans are spreading through shared folders

In the Control Panel, update the drivers. If still unsuccessful, delete those adapters, restart your workstation and reinstall drivers. Helpful to have another workstation nearby in case you need to download the drivers from the Internet.

1. check if there are lights on the specific router port where you have connected the Vista (e.g. if it is on port 2, check if there are lights on #2 at the front panel of the router).
2. check the ip address by going to command prompt (click start-run-type cmd press enter. on the command prompt, type ipconfig/all)
3. ip address should be similar to what your Windows XP is getting. Subnet mask, gateway, and DNS servers should be identical.

Eg. If XP has a 192.168.1.100 IP, your Vista should have 192.168.1.x IP address where x is a variable number other than 100.

4. If your IP address, subnet mask, default gateway, and DNS seems aligned for both PCs, check your browser settings. Open IE, go to tools, internet options, network connection and make sure that never dial a connection is selected.

yup..i have a symantec antivirus..i also turn off the firewall of my computer.

Try changing the driver for your HP LJP3005 on your XP machine. Use it with the HP LJ Series II driver.

what version of vista are you using, this is a very important piece of information, vista home flavors are not very network friendly,I recommend that you keep using XP until a few service packs are out for vista. If your using ultimate then something else would be wrong, possibly a setting on the vista box, Im not real sure how vista's authentication works but if they changed it enough then it might require a compatiblity mode or something in order to authenticate with 2000/xp, but then again i could be wrong and vista might authenticate exactly the same way as 2000/xp, try setting an xp box up as a server and see if the vista box can authenticate with it, if so then maybe 2000 is the problem, sorry i couldnt give an actual solution but im still new to vista myself and dont have any pc's that will run it, my good computers are all macs.
