We have created in SP3 c1 an System external reference, after migration in SP5 cp7, we try to modify the URL, we have this error : (look attachments for the screen)
Objet référence externe système, Propriété Chemin d'accès : Link already exist.
But the URL it's changed as well.
Edit : it's work with Windows XP, but with Windows 2008 R2, the trouble appear.
Someone have the same trouble?
Sorry for the delay of my response
I have created a system external reference on MEGA SP3 and i upgraded this environment to MEGA 2009 SP5 CP7, but when i try to change the URL (on Windows 2008 R2)i do not reproduce the similar behavior.
If you have further information please react on the topic.
