cannot "net use" across subnets using ipv6

I have 2 ipv6 subnets. 2001::1/64(vlan56) and 2003::1/64(vlan93) on a cisco nexus. computers on each vlan can ping each other thru ipv6 with no problems. I can perform a net use from within a subnet but when going across subnets, I get the "the network path was not found". This is what I'm doing
PC1 ipv6 address=2001::1885:2ef7:7f73:7434
SERVER1 ipv6 address=2003::250:56ff:fe8e:f
mapping a drive from PC1 to SERVER1
net use y: \\2003--250-56ff-fe8e-f.ipv6-literal.net\c$

Hi!
Keep in mind that both NetBIOS and WINS are not compatible with IPv6! Perhaps you need to disable these in your network...
But now to your question: A) Check the routes on all corresponding systems! (route print / netsh.exe)
B) A /64 route is actually a host route in IPv6! (Like a /32 in IPv4).
C) The IPv6 address used in that "NET USE" statement looks weired! Normally, IPv6 addresses are surrounded by square brackets (s.th. like [2001:BFE:: ...] Furthermore, they have NO DNS suffix at all -- as they are IP addresses, right?
D) Final thoughts: The addresses you stated are all Global IPv6 addresses. That means they might need to be enabled to pass firewalls (depending on the structure of your network). You might consider adressing the hosts using site-local addresses (FD00...), if they are at the same site...
