Repeatedlty prompted for username/password, even when correct

[Ledigimate]

A client has a home network, connecting three computers:

PC1: Main desktop with WinXP Pro SP3
PC2: Laptop with WinXP Pro SP2
PC3: Desktop with WinXP Pro SP2

An administrator account with same username and password exist on all three
PCs. When attempting to connect to PC1's shared folders from PC2 or PC3,
one gets prompted for a username/password repeatedly, even after supplying
the correct username and password. All three PCs are on the same workgroup.
Simple file sharing turned off on PC1. What could be wrong?

Probbaly because SP3 is not on all three.

After entering account / password, are the clients able to connect and access
the resources? If so, then your clients aren't caching the access token.

If the clients aren't connecting at all, check the Local Security Policy.

HI
You need to configure the specific Sharing on each computer.
Make sure that the Software Firewall on each computer allows free local
traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should
be Off, and the active Firewall has to adjusted to your Network IP numbers
on what is some time called the Trusted Zone (consult your 3rd Party
Firewall instructions.

Thank you, Jerry, Chuck, and Jack, for your suggestions. However, the
behaviour was caused by something I could never have guessed - a missing
registry value on PC1. I've learned something valuable. Here's the steps
that led up to my finding the cure:

I've created a batch script that contained the following:

NET USER TestUser testpassword /ADD
NET LOCALGROUP Users TestUser /DELETE
NET LOCALGROUP Administrators TestUser /ADD

which was then run on PC1. I've created another batch script just like it,
but with one additional line

NET USE * "\\PC1\Sharename" testpassword /USERC1\TestUser

(PC1 and Sharename substituded with the actual names) which was then run on
PC2. PC2 displayed the following error:

System error 1130 has occurred. Not enough server storage is available to
process this command.

This error message was all I needed to find the cure. A friend of mine,
called Google, searched and displayed some links related to this error. I
followed a few links and found the cure. The following Microsoft KB article
has the steps to add the missing registry value:

http://support.microsoft.com/default.aspx/kb/285089

Another article suggested using the value 21 (decimal) and said to increase
this value with increments of 3 (if 21 doesn't work) until the correct value
is found.

Most computers don't need this registry value, which is why it was absent.
After adding the value to the registry on PC1 and restarting the computer,
the shares on PC1 could be accessed.

Thank you Google

Hi
Yap, once you have a specific error it is much easier to solve a problem.
Glad you got it under control.
