Speed up your web access with opendns, a high speed DNS server that's free!

www.opendns.org

DNS Servers:
208.67.222.222
208.67.220.220

'm using nslookup on Windows. Why does each response point to your server at resolver1.opendns.com, with address 208.67.222.222, instead of to the domain in question?

nslookup, on Windows computers, appends the default local domain name of the Windows machine to the query. You can work around this by appending a trailing period to the domain(s) you request.

Example:
Instead of nslookup www.craigslist.org
you should use nslookup www.craigslist.org.

Note the trailing period after the .org — critical.

PC Anywhere firewall ports

Port PCanywhere
PCanywhere uses a range of ports.
When connecting, PCanywhere first sends a UDP packet to ping whether the system is alive. If the user doesn't know the IP address, PCanywhere will ping the entire local address range with these packets looking for servers. These scans are frequently seen by home users from their neighbors.

These UDP pings are sent to both ports 22 and 5632 (in hex, 0x0016 and 0x1600 respectively). The intended port was 5632, but a programming bug swapped the bytes in order versions.

PCanywhere will not work through a firewall because the UDP packet must go through in both directions.


22 (UDP)
Used in older versions, though newer version still use it for backwards compatibility.
5632 (UDP)
Used to "ping" the host in order to check its status (whether the target host is running PCanywhere, and if the service is currently busy).
5631 (TCP)
Remote control runs over this port
65301 (TCP)

Error message: Not enough server storage (Net Share access denied)

Not enough server storage
Not enough server storage is available to process this command.

Not enough memory to complete transaction. Close some applications and retry.

These error messages can indicate the IRPStackSize bug on the other machine (the server that has the share). On that computer open the event log and check for event ID 2011. If this is present, it is a strong indication for this particular bug.

To repair it, you have to reset the IRPStackSize parameter back to its default value of 15 on the server where the share is.

HKEY_LOCAL_MACHINE
 \SYSTEM
  \CurrentControlSet
    \Services
     \lanmanserver
      \parameters

Check for the presence of a value named IRPStackSize. If it doesn't exist, create it as type DWORD. With base set to decimal, enter the value 15.

Reboot the computer.

One frequent culprit is Norton AntiVirus, which tends to change this parameter.

Check also this Microsoft Knowledge Base article. It does not mention Windows XP, but applies to XP as well.
