I have an XP Pro and XP Home on my home network. I can ping my XP Home from
XP Pro but not the other way around. Therefore, I can access the shared
folders on my XP Home from XP Pro but not the other way around. Can anyone
tell me what I did wrong on my XP Pro? Thanks for your help.

I didn't turn on ICF. ICF/ICS service is started on XP Pro.
 
ICF is on on the Pro. machine? That could be the problem. Did you enable
file and printer sharing on the Pro. machine?
 
Hi Scott,
Thanks for your prompt response. No, I didn't have ICF turned on my XP Pro
machine. How to enable file and printer sharing on the Pro. machine? I
thought it is on if the service ICF/ICS is started. I am also worried about
XP Home cannot ping XP Pro. I think somehow XP Pro is refusing the incoming
traffic.

Bill,

Are you running both Client for Microsoft Networks, and File and Printer Sharing
for Microsoft Networks (Local Area Connection - Properties), on each computer?
Do you have shares setup on each?

On any XP Pro computer, check to see if Simple File Sharing (Control Panel -
Folder Options - View - Advanced settings) is enabled or disabled. With XP Home
and Pro together, you need to have SFS properly set. In this case, you probably
need to enable SFS.

With XP Pro, if SFS is disabled, check the Local Security Policy (Control Panel
- Administrative Tools). Under Local Policies - Security Options, look at
"Network access: Sharing and security model", and ensure it's set to "Classic -
local users authenticate as themselves".

With XP Pro, if you set the Local Security Policy to "Guest only", make sure
that the Guest account is enabled, thru Local User Manager (Start - Run -
"lusrmgr.msc"), and has an identical, non-blank, password on all computers. If
"Classic", setup and use a common non-Guest account, with identical, non-blank,
password on all computers.

For XP Home, OR for XP Pro with Simple File Sharing enabled, make sure that the
Guest account is enabled (for XP Pro, thru Local User Manager (Start - Run -
"lusrmgr.msc")), on each computer.

Check the software firewall (ICF). You need to configure it for file sharing,
by opening ports TCP 139, 445 and UDP 137, 138, 445, and / or by identifying the
other computers as present in the Local (Trusted) zone. Firewall configurations
are a very common cause of (network) browser, and file sharing, problems.

Cheers,
Chuck

Hi Chuck,
Thanks for your help. I checked both computers. They were configured as you
suggested. Please see my comments in your note. But I still have the
problems. Here are what I found.

1. Cannot ping XP Pro from XP Home. I found that there is a "IP Security
Policies on Local Computer". There are three items. 1) Client (Respond
only). 2) Secured Server (requires security): For all IP traffic, always
require security using Kerberos trust. Do NOT allow unsecured communication
with untrusted clients. 3) Server(requires security): For all IP traffic,
always request security using Kerberos trust. Allow unsecured communication
with clients that do not respond to request.

2. Be able to access the shares on XP Pro through IP address. The computer
name of my XP Pro is tigger, ip is 192.168.0.100. I am able to do "net use
s: \\192.168.0.100\tools" but not "net use s: \\tigger\tools".

3. Cannot share the printer on XP Pro. The printer on XP pro is not visible
thru "Add a Printer" from XP Home.

Am I supposed to see the other computer through " my network places"? Or
even "view workgroup computers"? Thanks for your help.

Yes, I have SFS enabled.

Bill,

How do you check / set "IP Security Policies on Local Computer"? What settings
did you try?

If the other computer is in the same workgroup, you should see it, and its
shares, in both Network Places AND Workgroup Computers.

With SFS enabled, the Guest account is absolutely required. Did you enable the
Guest account on XP Pro using lusrmgr.msc?

Your first post says "ICF/ICS service is started on XP Pro". Your recent post
says "I don't use ICF". Please explain the conflict.

Please provide ipconfig information for each computer.
Start - Run - "cmd". Type "ipconfig /all >c:\ipconfig.txt" into the command
window - Open c:\ipconfig.txt in Notepad, copy and paste into your next post.
Identify operating system (by name, version, SP level) with each ipconfig
listing.

From each computer, test shares visibility (use actual name / address of each
computer as appropriate):
Start - Run then:
1) \\ThisComputerByName
2) \\ThisComputerByIPAddress
3) \\OtherComputerByName
4) \\OtherComputerByIPAddress
Report visibility of shares / error displayed in each test (8 tests total).

Cheers,
Chuck

Hi Chuck,
I found the problem. I am using ZoneAlarm. I need to add the subnet to the
"trusted zone". Thanks for your help still. I learned a lot from you.

Aha. Zone Alarm.

Thanks for the update, Bill,
