SAPGui 720 and RRMX - RFC Error with a Message server

[Former Member]

I am testing SAPGui 7.20 before installing it on all workstations. I found an error RFC_ERROR_COMMUNICATION in the following situation.

Client side:

WIndows XP SP3

Office 2003

SAPGui 720 + patch 2 (gui720_2-10007878.exe)

BI 7.0 ADDON FOR SAP GUI 7.20 (bi720sp02_200-20006596.exe)

BW 3.5 ADDON FOR SAP GUI 7.20 (bw350gui720_2-20006857.exe)

Server side:

Installed the following notes: 1471630, 1499568, 1477686, 1473879

I connect to P1B (Production systrem) with my login/password. Then I launch RRMX and the following error appears:

RFC_ERROR_COMMUNICATION

SAP_CMINIT3 : rc=20 > Connect to SAP gateway failed

Connect_PM GWHOST=tosatti, GWSERV=sapgw50, SYSNR=50

LOCATION CPIC (TCP/IP) on local host

ERROR hostname 'tosatti' unknown

TIME Fri Sep 10 10:37:09 2010

RELEASE 720

COMPONENT NI (network interface)

VERSION 40

RC -2

MODULE nixxhl.cpp

LINE 183

DETAIL NiHLGetNodeAddr: hostname cached as unknown

COUNTER 2

This error happens only on Production system. On Development and Quality systems it is ok. The difference between these systems is that Production has a message server (po1bwsc.sapmi.telecomitalia.local) and a Group server defined

(PROD_P1B that leads to 4 application servers).

If I force the application server to logon to po1bwsc.sapmi.telecomitalia.local everything works well, but using the

group server I get the error above.

Furthermore I found out that:

if I add the IP address of the GWHOST (tosatti in this case, but I have also donald and alexey) in c:\windows\system32\drivers\etc\hosts file, everything works fine.

Please notice that with SAPGui 640 there is not this problem, even without adding the above IP addresses to etc\hosts file.

How can I avoid this problem?

Thanks

We changed a parameter in the application servers to get them working correctly.

What parameter did yiou have to change for this?

We are experiencing same issue.

Thanks in advance!
