WLAN XP & W2K -file sharing

[Alan]

I have just set up a WLAN between my XP Home & W2K Pro
machines using a DSL 604+ wireless ADSL Router. I have the
internet connection sorted (which I though would be a
problem due to the attitude of my ISP) and both PCs access
the internet independently. On my W2k PC I can see and
share the XP shared folders- however, the workgroup cannot
be accessed from the XP PC. I cannot even see the W2K
machine or workgroup on the XP PC.
I set up accounts with the same user name and password on
both machines, created a "Shared" folder on W2K, granted
(what I thought were) all the relevant permissions on the
W2K PC, but still this final part eludes me. I have tried
adding a Network Place, but I get error regarding server
permission.
I realise that permissions can be rather byzantine in W2K,
but if there is something in the security policies etc
that will resolve this I have missed?
(a few tutorials have helped, but most are aimed at XP-
98/ME rather than my combo)

Are either of your machines running a firewall. If so,
which one?

I disabled the freeware Sygate Firewall on the W2K PC and
now I get 2 messages in the dialogue box when I attempt to
view network- one informing me (as before) that the
Workgroup is not accessible, and one informing me that the
user has not been granted the requested logon type at this
computer (on the XP PC)
I have reviewed the settings in the Local Security
policies, but cannot see anything obvious.
In User Rights Assignment I have enabled both named PCs as
able to access the PC from the network.
