I am currently working on creating push/pull replication
using

win server 2003
win xp
sql server management express
and
win 7 as an option

when

publication n subscription is created on the same machine push replication is successfully done

the real problem arises while trying for pull and push replication on other machine in the network

publication and subscription are created
but when syncronization is done through 'mobsync.exe' in win xp
or through 'sync center' in win 7 it fails
n
the error it shows is as follows

in winxp
error:- subscription cannot be propogated

while in win 7

error:- ms sql server cannot save security changes

(after asking for sql authentication login and password)

wrong section post? It should've been posted under Microsoft SQL Server.
