system error #5 access denied

[Guest]

I hv this network, with server 2000 and winXP as clients. I've checked the
all the connection, there seems to b ok overall. Internet is fine, i can
access other's shared folders. Server can see me and open my shared folder as
well. But, dont know where or what went wrong, i cant open file from the
server. So what can i do now? Please. its been days now still i cant find the
solution. Thank u vey much.
