I am working on XI 3.0 running on Windows 2003 server and Oracle 9.2.0.6.

When trying to add my production system to the TMS I get the following error:

RFC communications error with system/destination DOM_CTL 
Message no. XT101 

Diagnosis 
An RFC error occurred in the TMS communications layer. 

Target system: DOM_CTL.(000) 
Function: TMS_CFG_CREATE_A2D_REQUEST 
RFC message:Error opening an RFC connection. 

System response 
The function terminates. 

Procedure 
Correct the error and execute the command again.

I have followed the instrcutions from http://www.sapsuperusers.com/phpBB2/viewtopic.php?t=4 Configuring TMS adding a new instance to TMS - R/3 4.x and up

but i keep getting this error.

I have checked the profile, and made sure the drive is shared, but running out of ideas.....

I have created an SM59 connection to both my Dev and QA systems and these work....

Any thoughts??

hi barry, here im facing a severe problem with RFC connections

where does this sapgw00 file resides .

http://www.saptechies.com/rfc-communication-error-in-transports/

pls have a look at the link ,

Thnak you Rahul

The sapgw00 is in the /etc/services file (Unix) or /windows/system32/drivers/etc/services file (windows). This just activates a port to be used in the gateway process. Normally there should be an entry such as sapgw00 3300/tcp
