Problem accesing SAMBA server from Windows XP util_sock.c:write_data

[Mateo Vilar]

Dear sirs,

   I'm having problems accesing to a SAMBA server from XP clients. The
problems appear sometimes and consist in disconnections of the shared
resource, very slow connection or not connection at all. Normally, it works
(slow but it works) but suddenly it stops working. The samba log of one
machine having the problem shows this:

Here the log.smbd
