The U2000V1R5SPC600 for Windows server dont let duplicate trails names by default.
We found that in the U2000V1R5 we have to change this flag following this route:
C:/U2000/client/tools/usercfgtool and execute usercfgtool.bat.
You have to select the type of database, IP address of the U2000, and password of the database of the U2000.
For example for the SQL2000 the default user and password is: sa and Changeme123
We find the flag bISuniSDHTrailname and we double click the line. now we change the 1 to 0.
After we finish we restart the server following the guide to shutdown the server U2000.
The customer requires to duplicate the trails names. we change the flag in the etrans.cfg file as we did it in the earlier U2000V1R2, this time the flag didnt take efect.
If you are upgrade NMS version, it is very important to take in count this flag.
