smb not working to access pc network files

Hi there,

I recently upgraded to MacOS Ventura.

Formerly, on MacOS Monterey, I happily was accessing files (read and write, storing and deleting) via Samba Protocol on our company's pc server in the form of

Finder

"Connect to Server..." (K)

then, in a dialog box I wrote

"smb://"fileserverhostname"

Enter

and was presented with a dialog asking for my name and password.

After this I was presented a list of mountable volumes to choose from.

By selecting and okay-ing a name the respective volume was mounted.

Everything fine.

NOW on Ventura,

I still get as far as to the list of volumes, but access is denied in the form that the small window containing the list is shaking and I get an

"Access denied"

My System Admin has not changed a thing and I obviously am talking with the pc file server, but there has to be made a change in protocol on the Mac System side internally (without mentioning it maybe?)

I would very much appreciate help from an expert - maybe there is an older and a newer protocol involved and the "denial" is due to an unfortunate order of checks?

Or the tightened safety rules on Ventura are barring the way of reestablishing the former connection to the pc server?

It would suffice for me if this was "curable" via the shell.

Thanks in advance,
