FAQ Logon Problems
 Question: What do I do in case logon problems occur?
Always verify logon problems on a different machine as it sometimes might be a local problem with your workstation. Usually you will be able to see a pop up box if you are experiencing a networking error. In the case you get to the first screen, the logon screen, please check with a colleague to log on as this might be a permission problem related only to your user account. A networking error often will give you an error message with the code '10054 - connection reset by peer'. This is usually due to a broken network connection. Please verify this on an additional workstation. If you refer to your network administrator you can run a first basic diagnosis with the SAP tool 'NIPING' according to note 500235.
