Question

hi friend,

i cannot create a OLE DB ADO connection becuase it cannot access my SQL 2005 server. I was told my SQL server name has special chars therefor i have reisntalled with the new name now its something like this: 

DELL-101\madmax, where DELL-101 is machine name and madmax is server name. still the problem exists. How do i create a new conenction to my sql server from crystal reports?
