Help:DTC-Firewall-SQL server clustering

Hello All
I am having trouble of DTC to get working thru firewall
The setup we have is
Two web servers load balanced. Componets run off the web servers. (OS:2000 Server
Two SQL server clusered.(OS: 2000 advanced server)
Web servers and SQL Servers are in different domain separated by firewall
Components do not work if I set "transaction required". If I changed it to "Transaction suported" or "not supported" some componets do work
I tried suggestions from kb article
DTCPing: http://support.microsoft.com/?id=30684
Initially DTCping had some problem but for testing purpose we opened all ports on firewall. It worked
I tried another config suggestion
http://support.microsoft.com/?id=25036
When I apply the registry entries for ports mentioned in this article, it disabled Clustering service. I was not able to get it back until I revert back registry settings
I tried DTCtester utility, it doesn't work
Does any one know why it must be disabling the clustering service? or Have any other suggestions on configuration for DTC thru Firewall
Thank
MilsThanks Jeff
I tried the procedure you mentioned. but it did not help
I have already tried the DTCping utility. At first it did not work but then I opened all the ports on firewall. now DTCping works.
DTCtester.exe utility still does not run, it gives error

One of the error description refers to multiple netcards. Our SQL server has multiple netcards.
Any idea if there's any specific configuration for SQL Server using multiple netcards
Thanks
Milin|||1. Are the ports still open. If not then you need to open ports 445, 135,137-9, plus the ones you set in DCOMCNFG
2. Do you have an entry in each server of the cluster's host file with an entry to the destination server. and likewise on the destination for each of the Clustered servers
3. Does DTCPing work both ways now also
Jef
MCDBA, MCSE+I|||Yes. All ports are still open in both directions
I have entries in hosts files of both servers. I can access these servers using network names from each other
DTCping work in both directions
Thank
mil|||Did you actually set the ports with DCOMCNFG and reboot or did you just try the reg hack
If not then set DCOMCNFG on all servers to use the proper ports and reboot all servers
Other than that I cannot think of anything else
Good Luc
Jeff|||Mil
I am sorry then. In all my experience once I have had DTCping working I have had DTC working as well
