DFS file replication

S

Simon B. Nielsen

I've setup file replication between 2 servers - both domain controllers for
the same domain. First I created a root share and then a root replica -
everything went smooth. It has been running perfectly for a 1½ years until a
few weeks ago when the replication all of the sudden stopped from happening.

I've checked replication policy and both are set to participate in automatic
replication. Looking through the event log I found the following:

---
The File Replication Service is having trouble enabling replication from
NLBDC02 to NLBDC01 for c:\winnt\sysvol\domain using the DNS name
nlbdc02.nlbdom.local. FRS will keep retrying.
Following are some of the reasons you would see this warning.

[1] FRS can not correctly resolve the DNS name nlbdc02.nlbdom.local from
this computer.
[2] FRS is not running on nlbdc02.nlbdom.local.
[3] The topology information in the Active Directory for this replica has
not yet replicated to all the Domain Controllers.

This event log message will appear once per connection, After the problem
is fixed you will see another event log message indicating that the
connection has been established.
---

I started checking both servers. FRS is running on both and they can resolve
eachother. That leaves only the 3rd option which I cannot really check but
no computers or users have been added/deleted or modified during the last
few months at least.

What the hell can be wrong? Does anyone know if a recent patch has screwed
up DFS or something because nothing I do seems to work.

Best regards...

Simon

Looks like there is some problem with DNS. Check the DNS event log.
Can you please run the diagnostic tools netdiag.exe and dcdiag.exe in each
of the domain controllers and check if there are any errors reported?
These tools are available as part of the resource kit.

OK could not get DCDiag.exe to run - kept getting the following pop-up: The
procedure entry point DsIsMangledDnW could not be located in the dynamic
link library NTDSAPI.dll.

I tried reinstalling ADMINPAK.msi from both the service pack folder and from
the CD, but nothing helped.

Here's what NetDiag.exe returned:

This is clearly due to one of the following problems with DNS
1.Was there any new computer added into the domain with the same name as
that of DC?
2.Check if there are any invalid DNS records using the DNS snap in
(Star->Programs->Administrative Tools->DNS)
Go to Forward lookup zones and check the list of host records.
If there are any invalid entries, delete them
3.Check if both the name servers are listed i.e both the DNS servers should
be listed as name servers
4.Right click the domain name - Choose Scavenge Stale resource records and
Update server files and re start the DNS (menu - All tasks - Restart)
5.Check if there is a event log from MRxSmb in any of the ADS - System event
log with ID 3034
If so, check
http://support.microsoft.com/default.aspx?scid=kb;en-us;263208
""Connecting with Incorrect Computer Name Results in 3034 Warning""
5.Use the nslookup utility to check if the name lookup is correct - KB
article 200525
6.Check if the time is synchronized between both the ADS
6.Restart primary ADS and then the other ADS

Looks like there is some problem with DNS. Check the DNS event log.
Can you please run the diagnostic tools netdiag.exe and dcdiag.exe in each

These tools are available as part of the resource kit.

I've setup file replication between 2 servers - both domain controllers
for
the same domain. First I created a root share and then a root replica -
everything went smooth. It has been running perfectly for a 1½ years until
a
few weeks ago when the replication all of the sudden stopped from
happening.

I've checked replication policy and both are set to participate in
automatic
replication. Looking through the event log I found the following:

---
The File Replication Service is having trouble enabling replication from
NLBDC02 to NLBDC01 for c:\winnt\sysvol\domain using the DNS name
nlbdc02.nlbdom.local. FRS will keep retrying.
Following are some of the reasons you would see this warning.

[1] FRS can not correctly resolve the DNS name nlbdc02.nlbdom.local from
this computer.
[2] FRS is not running on nlbdc02.nlbdom.local.
[3] The topology information in the Active Directory for this
replica
has
not yet replicated to all the Domain Controllers.

This event log message will appear once per connection, After the problem
is fixed you will see another event log message indicating that the
connection has been established.
---

I started checking both servers. FRS is running on both and they can
resolve
eachother. That leaves only the 3rd option which I cannot really
check
but
no computers or users have been added/deleted or modified during the last
few months at least.

What the hell can be wrong? Does anyone know if a recent patch has screwed
up DFS or something because nothing I do seems to work.

Best regards...

If you get the event 3034 in any of the ADS, check
263142 Determining the Cause of an "MRxSmb 3034" Warning
http://support.microsoft.com/?id=263142



Ramya Priya said:
This is clearly due to one of the following problems with DNS
1.Was there any new computer added into the domain with the same name as
that of DC?
2.Check if there are any invalid DNS records using the DNS snap in
(Star->Programs->Administrative Tools->DNS)
Go to Forward lookup zones and check the list of host records.
If there are any invalid entries, delete them
3.Check if both the name servers are listed i.e both the DNS servers should
be listed as name servers
4.Right click the domain name - Choose Scavenge Stale resource records and
Update server files and re start the DNS (menu - All tasks - Restart)
5.Check if there is a event log from MRxSmb in any of the ADS - System event
log with ID 3034
If so, check
http://support.microsoft.com/default.aspx?scid=kb;en-us;263208
""Connecting with Incorrect Computer Name Results in 3034 Warning""
5.Use the nslookup utility to check if the name lookup is correct - KB
article 200525
6.Check if the time is synchronized between both the ADS
6.Restart primary ADS and then the other ADS
