Question : MSDTC Network Issue

Hi experts,

I just rebuild a Windows Server 2003 box and installed SQL Server 2005 (and SP1 for both).  I'm trying to establish communications between my server and a client's server.  I'm using dtctester.exe and receiving the following results:

(remotely from a networked box)
---------------------------------------------------------------------
C:\dtctester>dtctester dev [username] [password]
Executed: dtctester
DSN:  dev
User Name: [username]
Password: [password]
tablename= #dtc5960

ion manager, or the transaction manager is unavailable.

(locally from the SQL Server 2005 box)
---------------------------------------------------------------------
C:\dtctester>dtctester dev [username] [password]

I've checked the Security Configuration on the MSDTC tab of the "My Computer" section in Component Services, and the following are checked:
- Network DTC Access
- Allow Remote Clients
- Allow Remote Administration
- Allow Inbound
- Allow Outbound
- No Authentication Required
- Enable XA Transactions

I've also confirmed the regedit settings for MSDTC:

AllowOnlySecureRpcCalls = 0
FallbackToUnsecureRPCIfNecessary = 0
ServiceNetworkProtocols = 33
TurnOffRpcSecurity = 1

(Security folder)
DomainControllerState = 0
NetworkDtcAccess = 1
NetworkDtcAccessAdmin = 1
NetworkDtcAccessClients = 1
NetworkDtcAccessInbound = 1
NetworkDtcAccessOutbound = 1
NetworkDtcAccessTip = 0
NetworkDtcAccessTransactions = 1
XaTransactions  = 1

Any idea what's causing this or how to fix?

Thanks!
