Set server name as โSyn1โ. Using User1, Password1.ย In administrators group, so already has full access rights, full read/write permissions, and the only enabled user account on the NAS to date.
On PC1, all drives, files, NAS control etc etc are enabled and everything works entirely as expected.
I then move to PC2.
Web access via chrome (User1 Password1) gives complete access to the NAS DSM desktop, settings etc, exactly the same as on PC1
In both Network and Explorer, โSyn1โ clearly shows as a network device, so discovery etc working.
But, click on โSyn1โ in either Network or Win Explorer, pauses briefly, then requests username & password.ย Enter User1, Password1 โฆ and I get told theyโre wrong.ย ย Syn2ย shown in the pic above works fine โ itโs a DS420j, set to be replaced by this new DS923+
Same user and password on the same PC allows me to change any NAS settings in a browser !! but doesnโt allow access by any other method.ย Turning off Virus scanner makes no difference.
Creating a mapped drive or desktop shortcut โฆ I cut & pasted the password โฆ still get:
This is misleading, as the password is correct. (I blanked theย actualย username with XXXโs.)
Stumped, doesnโt cover itย โน
From PC2, via browser, I created a new user2, with admin rights.ย I canโt access that either, except via browser.ย From Explorer etc I get the same โthe specified network password is not correctโ
If you can figure this out, I will most certainly treat you to a coffee! (FYI I already subscribed to your YouTube vids.)
Additional info:ย Currently just a single user created on NAS. Both PCโs Win10Pro x64 up to date. Both โbeastsโ with masses of RAM and tens of TB storage.ย On same network, with same โWORKGROUPโ name.
I believe Iโve cracked it!
When setting up the NAS, I declined the option for detailed logging.ย However, I ventured into the โsimpleโ log on the NAS and selected โConnectionโ.
I found that the first PC was shown as connecting โ via [CIFS(SMB3)]accessed shared folder [V1]โโ
While PC2 was shown as failing trying to connect โfailed to log in via [SMB] due to [NTLMv1 not permitted]โ
Asking that nice Mr. Google, I found someone else had had similar problem, and solution was to enable NVLMv1 in the NAS.
However, if I go to this, DSM reads the riot act about it being insecure, and advising heavily against it.ย So, I left it alone.
So instead, I tried the opposite approach, and disabled NTLMv1 in the PCโs Registry. Figured it worth a try โฆ
Tried to log into a folder on the NAS, and voila!ย Straight in!!
Heading back to the Synology log, the second PC is now using the same [CIFS(SMB3)] ๐
It is as yet unclear as to what if any other problems may develop for other apps or processes due to this seemingly insignificant, minor change, but for now at least, I have full access to the NAS from all PCโS.
So should you encounter this strange issue again in future, youโll know where to look. I understand it can occur moving from DSM 6 to 7 (my old NAS is still DSM6.4).ย Old NAS is still accessible too, from all PCโs
Thanks muchly for trying to help.ย Iโll head off to YouTube and donate your coffee.
Regards,
ย Kevin
