Question : Error: (5) Access is Denined

I am getting an error saying Error: (5) Access is Denined when I try to copy a file.  What can I do to fix resolve this so I can copy files.

I tried to copy from Laptop1 to Desktop2.

The share on the Desktop2 PC is:
C:\Downloads
With security on the folder - Everyone = full control & all other boxes checked except Special Permissions which is greyed out.

I have tried removing the share and setting it up again.

Laptop1 is running XP Pro Sp1 with Workgroup = WORKGROUP     192.168.1.70
Desktop2 is running XP Pro Sp1 with Workgroup = WORKGROUP   192.168.1.30

I can see Desktop2 from Laptop1 when I use the IP address.

Both have all MS updates.
Both are running the Browser service
The Laptop1 has a user defined on Desktop2.  The same user on both PC's is configured as Administrator with the same password.  
Both have "Enable NetBIOS over TCP/IP" selected in the network card.

Laptop1 shows
C:\>net view
Server Name            Remark
------------------------------------
\\LAPTOP1
The command completed successfully.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters] Value Name: IsDomainMaster = False

Desktop2 shows
C:\>net view
System error 6118 has occurred.
The list of servers for this workgroup is not currently available
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters] Value Name: IsDomainMaster = True

Currently the Laptop1 is the Master Browser.  The Desktop2 should be the Master Browser.  When the Desktop2 is the Master Browser the above two Net View results are reversed.

I have the XP firewall turned off on both PC's.
I have ZoneAlarm Pro installed on both PC's.
I have the IP address of the Laptop1 installed in the Desktop2 ZoneAlarm Firewall Zones as Trusted.
I have the IP address of the Desktop2 installed in the Laptop1 ZoneAlarm Firewall Zones as Trusted.

I can Ping both ways with the IP address.

I don't have a domain setup and never have.
I don't have a WINS server setup and never have.

There is a router connecting the two.  It passes the following ports:
PORT 137 (UDP) for NetBIOS Name Service
PORT 138 (UDP) for NetBIOS datagram (Netlogon, Browsing)
PORT 139 (TCP) for NetBIOS session

Any ideas how I can fix this Access is denined error?

Thank you,

Answer : Error: (5) Access is Denined

You mentioned the security on the folder is Everyone full?
What about the sharing permission on the share?
