the problem i am having is close to what u are descriping. I am run'ng Kixtart 3.6 on the netlogon server running nt 4.0 & sp4. my resource DC are running nt 4.00 & sp 5. the logon scripts ware running fine for W9x but now the scripts run fine mapping to shares on some member servers but fail to map to shares on other memeber servers. the script also runs fine for all servers on another domain running SP4 on the DC and the member servers. it is also running fine on a domain running nt 4.0 and sp5 on the dc and the member servers.
