SystemServerConnectionInvalid interesting solve

[Scott Grinter]

Hi All,
Just joined - posting because I can never find anything useful on TM1 error messages.

I have a TM1 server 9.0SP3 running on laptop (dev) and today I couldn't log in.
Login Error:SystemServerConnectionInvalid
This error is normally associated with a server client version mismatch (normally older server).

Cause:
I use a server shortcut to start the server
"C:\blah\path\to\tm1\tm1s.exe" -z"C:\blah\path\to\TM1Data"
Recently I "cleaned up" this short cut and put changed the Target
from the default "C:\"
to "C:\blah\path\to\TM1Data"
Changed the target in the shortcut back and client connected again. Probably comes down to the rights to write!
There you go- probably not too interesting for most but could save someone a bit of time.

I have been using / building in Tm1 for years and was pleased to stumble upon the forum. Hoping I can post something a little more inspiring next time.
