Coonecting network drives

My brother had to install WinXp_sp2 from scratch, on both a laptop and a
desktop. Both works, except for sharing drives between systems.
Both are in the same workgroup, both allows have "MS File and Printer
sharing" activated, both can get to "Connect to network drive", browse to
the other machine and choose the shared disks, get a driver for them etc....
But neither machine can use the other disk, there always comes a small
window with:

Window caption: "Windows XP installer" (????)
Windows text: "Install and configure system components in
ControlPanel"

This with Sygate enabled or disabled

What components???


Also, on the Fujitsu-Siemens laptop (Amilo 1630) the Odyssey driver for WLAN
802.11b/g can't get an address from the Belkin router/AP (configured as AP)
without him shutting down Sygate firewall. When IP retrieved, the firewall
can be activated again....
(Advanced rule in Sygate: IP 10.0.0.0 - 10.0.0.255, 0.0.0.0 allowed all
traffic, network neighborhood allowed)

TIA
