I have had this 7425 for at least 5 years and network scanning (SMB) has always worked fine.
These last few months, however, it fails to work after a few days of working, just beeps and gives me the code 027-529
If I restart my PC, it will work again for a few days, before stopping again. I have tried to monitor when and why it stops but to no avail. I am on Windows 7 Professional SP1 64-bit. If I restart the Xerox it still fails to work.
I have changed my router (twice) and this hasn't helped it seems.
My Xerox dealer has been through all the settings with me, created new File Repositories etc and we have even set up scanning via FTP, which also works fine for a few days and then stops too.
The only thing which has really changed in the last few months is that I got another PC (Windows 8) and upgraded to MS Office 360 and had difficulty with file sharing and the new Excel crashing and (as I have got an MS Answer Desk contract) they logged onto my machine and fudged around with sharing settings and trust certificates etc - not sure what they really did to be fair, but perhaps they screwed with something which is affecting my scanning ?
I have just found something on the internet about SMB and SAMBA not working and to change a few settings in Local Security Policies, but this has not helped either.
I am now out of ideas really, other than buying a new scanner which seems ridiculous !
