win 10 machine can't access network shares on pdc, intermittent

I manage a small windows domain for my home/home office. It consists of a PDC running Windows Server 2003 SP1 (I know! it's old! etc.) and a hand full of computers with fixed private IP addresses (10.x.x.x):

3 Win 10-64 Pro

1 Win 8.1-64 Pro

2 Win 7 Pro (one 64-bit, one 32-bit)

1 Win XP-32

My intermittent problem for the past year or so is that one of the Win 10 machines occasionally (maybe 3 times/month) suddenly cannot access any network shares on the PDC. This causes a number of automated backup processes to fail. When this happens:

(machine names and IP addresses changed to protect the guilty! :-)

- it can ping the PDC by name, so DNS is not the issue

 C:\Users\XXX>ping MyServer
    
    
 Pinging MyServer [10.x.x.x] with 32 bytes of data:
    
 Reply from 10.x.x.x: bytes=32 time=1ms TTL=128
    
 Reply from 10.x.x.x: bytes=32 time<1ms TTL=128
    
 Reply from 10.x.x.x: bytes=32 time=1ms TTL=128
    
 Reply from 10.x.x.x: bytes=32 time=1ms TTL=128
    
    
 Ping statistics for 10.x.x.x:
    
 Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    
 Approximate round trip times in milli-seconds:
    
 Minimum = 0ms, Maximum = 1ms, Average = 0ms

- this fails, with a fairly long delay before the error message appears (perhaps 2 minutes):

 C:\Users\XXX>dir \\MyServer\backupfiles
    
 The semaphore timeout period has expired.

- and yet this works:

 C:\Users\XXX>dir \\10.x.x.x\backupfiles
    
 Volume in drive \\10.x.x.x\backupfiles is zzzz
    
 Volume Serial Number is 10C0-79BC
    
    
 Directory of \\10.x.x.x\backupfiles

 7 File(s) 1,648 bytes
    
 2 Dir(s) 4,306,067,456 bytes free

- it can connect to network shares on other machines

The only way I can clear this is by rebooting the win 10 machine, after which all is well ... for perhaps a week.

I'd be grateful for any insights anyone may have.
