Upgrade Solution Manager 7.1: Error in phase INPUT_OS_USER_PWD (Prep. J2EE)

Dear all,

an upgrade from solution manager 7.0 SPS25 to solution manager 7.1 on a windows server 2008 r2 installation with mssql server database stopps in phase INPUT_OS_USER_PWD with the following error in logfile NET_VALIDATE_USER_PASS__ISP_04.ERR

System error 53 has occurred.

The network path was not found.

The logfile INPUT_OS_USER_PWD_ISP_04.LOG shows a command which isn't applicable in that syntax manually:

net use it finishes without error. So it should not be a network/firewall etc. problem. The same happens when I replace the dot with the hostname. All commands can be executed on a windows server 2003 installation.

I found a similar SDN forum entry (), but the .jar and .class files mentioned there are replaced by other ones in the SOLMANUP subdirectories.

For my regular SAP message I did not get any replies. Can anyone advise how to continue with the upgrade in this situation?

Regards

Björn Tralls
