Hello Takashi,

sorry for the delay.  I don't manage the server in question, so I can't call 'smbstatus' directly on it, but if it's any indication of version there is a path :

/usr/share/doc/samba-4.10.16/

Also, attached is the /etc/smb.conf file, somewhat redacted.

Thanks for looking at this.
Philippe

Hello Cygwin list,

Since updating my Cygwin installation to the latest version, I am having
the problem of  "Too many levels of symbolic links" on certain network
drives, that was reported in other threads.  I tried replacing the
'cygwin1.dll' with the snapshots from 2022-02-17 and 2022-03-01
(x86_64).  This did fix the link to one of the network drives, but not
others.

The mount command in my case gives :

$ mount
D:/cygwin64/bin on /usr/bin type ntfs (binary,auto)
D:/cygwin64/lib on /usr/lib type ntfs (binary,auto)
D:/cygwin64 on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)
L: on /cygdrive/l type cifs (binary,posix=0,user,noumount,auto)
V: on /cygdrive/v type smbfs (binary,posix=0,user,noumount,auto)
W: on /cygdrive/w type smbfs (binary,posix=0,user,noumount,auto)
X: on /cygdrive/x type smbfs (binary,posix=0,user,noumount,auto)
Y: on /cygdrive/y type smbfs (binary,posix=0,user,noumount,auto)
Z: on /cygdrive/z type smbfs (binary,posix=0,user,noumount,auto)

No problem with the local drives, and I can now go to the X: drive
thanks to the recent snapshot.  But not other 'smbfs' ones :

$ cd Z:
-bash: cd: Z:: Too many levels of symbolic links

Any ideas what could be wrong ?  It seems to be limited to certain SAMBA
shared drives.
Hmm, could you please provide the version of samba
and hopefully smb.conf file if possible?
I cannot reproduce your problem, so more information
