TAO NT Naming Service Stopped on DTW

[Former Member]

One of my customers recently upgraded to SAP B1 PL04 but for some reason the Data Transfer Workbench has stopped working on all client PCs, giving a error message "Connection to SAP2\SAPB1SERVER has failed Error Code -131 Connection to license server failed; if license server is invalid, correct it; if TAO NT Naming Service has stopped, activate it and restart license manager.  I looked up the issue on the forums but so far I haven't foudn the solution.  Fixes that I've tried include restarting the server, restarting the TAO NT Naming Service, restarting the License Manager, cleaning up the registry entries, making sure that both the firewalls are disabled, using the IP addres in stead of the server name and, finally, reinstalling the entire client and DTW.  THe DTW works perfectly on the server itself and the company databases are visible on the clients.  If you enter the incorrect username or password it indicates that you are using the incorrect login details, but the correct details still return the same error message.  Is there anything that I'm missing?

THanks, everone, for your help.  It seems that the problem was related to the antivirus AND the server location.  By disabling the antivirus and using the IP address the problem seems to have been solved.

Hi,

This is the issue of security policies. Ask your IT team for proper rights. Even you can try with admin login or Run SAP as administrator.

    SAP Business One doesn't start and License Server Selection screen comes up

    SAP Business One generates this error message when logging on: "Connection with license server failed"

    On License Server Selection this error occurs: "Connection to license server failed; if license server address is invalid, correct it; if TAO NT Naming Service stopped, activate it and restart License Manager"

Cause

License Manager: Dependencies of SAP Business One License Manager to the  TAO NT Naming Service, in some cases Firewall settings might prevent running the TAO NT Naming Service.

RSP: Firewall might block TCP/IP and relevant port range when RSP agent is not included in the firewall policy list.

Solution

    1. Check disabling the Firewall settings of relevant Virus scanner  software / Host Intruder prevention software (e.g. McAfee)

    2. Restart the TAO NT Naming Service & SAP Business One License Manager  / Restart the SAP Business One RSP Agent Service

If the firewall is identified as the root cause, please review the firewall policy and settings.

Thank you, Kennedy T,

But I'm only having the issue with the DTW.  I've also done what this note suggested.  As per Naga's response, I also disabled the anti-virus on both the server and client, restarted both and still have the same issue.

Hi Stephan Botha,

Any anti-virus running?

[Former Member]

Hi Naga Rajan,

Yes, the customer is using Sophos.  We tried disabling it on the Server and client as well, but we still have the same problem.

[kothandaraman_nagarajan]

Hi,

Did you restart the machine after disabling?

[Former Member]

Yes.  we also restarted the Licence Manager and the TAO NT service during this period.  Still no dfference.

[kothandaraman_nagarajan]

Hi,

Try to rename folder of Sophos and then  try.

Thanks,

Sorry it took so long to reply.  I tried this as well now.  Unfortunately it still made no difference.
