Re: SAP

Probably the logs from C:\Program Files (x86)\SAP\SapSetup\LOGs would be of more interest than the SAPlogon or SAPGUi trace files, though it's hard to be certain.  It does appear there is something screwy with the installation on this workstation that isn't happening on the others, and since you say the SAPGUI install is identical to the others, then maybe something else is interfering.  Have you scanned the workstation for malware?  Do they have third-party toolbars and browser helpers installed (i.e., Google Toolbar, Ask Toolbar, etc)?  Can you ping the SAP server you're trying to reach from the workstation?  I would try to make the workstation as clean as you can, and then try again with a fresh install of the SAPGUI.

For the fresh install, rather than just uninstalling and reinstalling, it may be of some benefit to truly clear all traces of the old installation away.  Uninstalling alone doesn't do this.  Finding all the folders and registry entries is a bit different depending on whether it's Windows 7 vs Windows XP, etc, whether it's 64-bit vs 32-bit, and whether this was an upgrade of an older SAPGUI version or a clean install where no SAPGUI previously existed.  The steps I take to do this on my test workstations go something like this:

1. Run the uninstaller from Control Panel... Add/Remove Programs.  Be sure to also uninstall extra components, such as SAPSetup Automatic Workstation Update Service or SNC Client Encryption, etc.  Basically anything associated with SAP.
2. Use REGEDIT to delete the registry keys:
   1. HKCU\Software\SAP
   2. HKLM\Software\SAP (for 32-bit Windows)
   3. HKLM\Software\Wow6432Node\SAP (for 64-bit Windows).
3. Delete any of the following folders which exist (depending on OS and upgrade vs install, not all will be present):
   1. C:\Program Files (x86)\SAP (for 64-bit)
   2. C:\Program Files\SAP (for 32-bit)
   3. C:\Program Files\Common Files\SAP Shared
   4. Windows 7 (or Vista or 8):
      1. C:\Users\<username>\AppData\Roaming\SAP (for Win7, and note that AppData is a hidden folder)
      2. C:\Users\<username>\AppData\Local\SAP
      3. C:\Users\<username>\AppData\Local\VirtualStore\Program Files (x86)\SAP
      4. C:\Users\<username>\SapWorkDir
   5. Windows XP:
      1. C:\Documents and Settings\<username>\Application Data\SAP
      2. C:\Documents and Settings\<username>\Local Settings\Application Data\SAP
      3. C:\Documents and Settings\<username>\SapWorkDir
4. Delete the following files if found outside of the above folders:
   1. C:\Windows\saplogon.ini
   2. C:\Windows\sapmsg.ini
5. Delete temporary files where possible:
   1. C:\Windows\temp\*
   2. C:\Users\<username>\AppData\Local\Temp\*
   3. C:\Documents and Settings\<username>\Local Settings\Temp\*
6. Remove SAP-specific entries from C:\Windows\System32\drivers\etc\services
   1. Be careful editing this file, and if in Win7 you will need to first open Notepad with 'Run as Administrator'.
   2. SAP entries will start with 'sapms...', 'sapdp...', and 'sapgw...' and will usually be at the end of the file.
7. Reboot, and reinstall.
