Quick look
 Code:
[IBB Kondor]
CLASS=DISK
TARGET=F:
PATH=\\dc-034\netapps$
DESC=Netapps
CLASS=DISK
TARGET=G:
PATH=\\dc-034\USR$\%USERNAME%
DESC=USERSHARE AUTOCAD
CLASS=M:
PATH=\\dc-034\acad$
DESC=Autocad 
CLASS=O:
PATH=\\DC-034\ACAD DIRECT$
DESC=AUTOCAD SYNCHRONISATIE
PRIV=GUEST
GROUPS=GS_IBB Kondor_ACAD
OUS=

will not work as defined. You have multiple duplicate values in a single resource definition.

"CLASS=M:" is incorrect. CLASS can only be one of DISK, PRINTER, MESSAGE, or COMMAND. You should change these to CLASS=DISK and TARGET=d: values.

"[IBB Kondor]" represents a single resource definition - it can have only ONE set of CLASS, TARGET, PATH, DESC, and similar attribute values. It seems like you're using it as a grouping of similar resources. If this is what you intend, you should do this instead:
 Code:
[IBB Kondor 1]
CLASS=DISK
TARGET=F:
PATH=\\dc-034\netapps$
DESC=Netapps
[IBB Kondor 2]
CLASS=DISK
TARGET=G:
PATH=\\dc-034\USR$\%USERNAME%
DESC=USERSHARE AUTOCAD
[IBB Kondor 3]
CLASS=DISK
TARGET=M:
PATH=\\dc-034\acad$
DESC=Autocad 
[IBB Kondor 4]
CLASS=DISK
TARGET=O:
PATH=\\DC-034\ACAD DIRECT$
DESC=AUTOCAD SYNCHRONISATIE
PRIV=GUEST
GROUPS=GS_IBB Kondor_ACAD
OUS=


Start by making a copy of the config file and then remove all of the entries and comments except ONE resource record (and the COMMON section) - see if it works. Duplicate the resource record and modify it to create the second record & test. Repeat this until you get comfortable with the format of the config file and add the remaining resources.

Also, I don't believe that %USERNAME% will work - reread the section on Path Rewriting. The format for these should be
PATH=\\dc-034\USR$\&USER&
not
PATH=\\dc-034\USR$\%USERNAME%

Let's fix these issues and see if we can't get things working.
