Hi,
Based on my research, please try the following:
1.
Try to access the share folders by “\\XXX.XXX.XXX.XXX<IP Address>\folder” and see how it works.
2.
If you have installed some security software (firewall, anti-virus, anti-spyware, etc.) on this Windows 7 computer and
Windows server 2003 R2 server, please also temporarily disable or remove it and check if it works.
3.
Enable
NetBIOS over TCP/IP on all computers on the Windows 7 computer:
1)
Go to “Control Panel\Network and Internet\Network Connections”.
2)
Right-Click on the connection and choose Properties.
3)
Click “Internet Protocol (TCP/IP) Version 4” in the list.
4)
Click Properties, and then click Advanced.
5)
On the Advanced TCP/IP settings windows, go to “WINS” tab.
6)
Under NetBIOS setting, click “Enable NetBIOS over TCP/IP”, and then click OK.
4.
On the Windows 7 computer, please go to “Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings” and ensure that
the following items are turned on:
Network Discovery
File and printer sharing
And this one is OFF:
Password protected sharing
Hope this helps.
Thanks.
