samba - Dec 2003 - help regarding migration of user from nt to linux

We are in a process of migrating our windows nt server to linux and hence users
also.We are facing
some difficulty regarding this.We tried to do the steps mentioned in the article
written by you in the pc
quest magzine.

While running the command :
 net rpc vampire -w domain-name -U Administrator%password
follwoing message is coming :
Failed to fetch domain database : NT_STATUS_ACCESS_DENIED

Which access it is refering ?

While looking the system log in event viewer on winnt following messge are
coming :

The full synchronisation request from the server MKP failed with the following
error : Access is denied.

While running following command :

net rpc join -S NTSERVERNAME -w NTDOMAINNAME -U Administrator%password 

at linux it is coming : Joined MAIL Domain

And also at server manager this host is added but system log is telling that :

The session setup from the computer MKP failed to authenticate.The name of the
account refrenced in the
secuirty database is MKP$.The access is denied.

MKP is the host name of linux server.

while running the command net rpc testjoin

message is coming : join to 'MAIL' is OK.

Where MAIL is the domain name.

Kindly suggest some solution to rectify the problem.

I shall be highly thankful to you.
