Re: [Samba] DRS Replication between two DC's Failing




Hi James

Thanks for your response.

hots -t A iumsvrpdc    (use it's fqdn as well)  I have verified it with the
FQDN which says that the record iumsvrpdc.iumnet.edu.na exists

Search for 'iumsvrpdc' objectGUID

ldbsearch -H /usr/local/samba/private/sam.ldb '(invocationId=*)'
--cross-ncs objectguid : it shows 2 records found

# record 1

dn: CN=NTDS
Settings,CN=IUMDCDP01,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=iumnet,DC=edu,DC=na

# record 2

dn: CN=NTDS
Settings,CN=IUMSVRPDC,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=iumnet,DC=edu,DC=na

# returned 2 records

# 2 entries

# 0 referrals

host -t CNAME objectGUID-for-iumsvrpdc._msdcs.samdom.example.com

host -t CNAME iumsvrpdc._msdcs.iumnet.edu.na

iumsvrpdc._msdcs.iumnet.edu.na is an alias for
27182378-a9c7-451e-bb95-7b2172a5f311._msdcs.iumnet.edu.na


Reference the wiki if needed.  https://wiki.samba.org/index.

Just to confirm you are attempting to replicate from 'iumsvrpdc' to '
iumdcdp01.iumnet.edu.na'? YES


Please assist to resolve this issue.
