To work around this issue, edit the SizReqBuf registery value using the following steps:

1.Start Registry Editor (Regedt32.exe or Regedit.exe).

2.Go to the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \LanmanServer\Parameters

NOTE: The above registry key is one path; it has been wrapped for readability.

3.Create the SizReqBuf value using the following information:

Value Name: SizReqBuf Data Type : REG_DWORD Data : 512 - 65536 (bytes in decimal) Default : 4096

For Pro/E use a value of 5120

NOTE: The exact value that works best in a given environment will depend on the specific configuration of that environment, but 14596 is a value that has been shown to work well in a fairly standard Ethernet environment.

4.Close Registry Editor and restart your computer.
