If you send a large recordset over a very slow modem line from a computer that is running Microsoft Windows 95 or Microsoft Windows 98, you may receive the following error message on a blue screen:
An exception OE has occurred at 0028:C14C0CC5 VXD PPPMAC (01) + 000030B5 called from 0028C184EA2C in VXD PPPMAC (04) + 0000935C
The error message occurs because the modem connection is too slow and cannot support the packet size that Windows is using.
To resolve this issue, reduce the maximum packet size to a size that the connection can support. In Windows 95 or Windows 98, you can modify the default Maximum Transmission Unit (MTU) setting:
  1. Click Start, point to Settings, click Control Panel, and then double-click Network.
  2. On the Configuration tab, click Dial-Up Adapter, and then click Properties.
  3. On the Advanced tab, click IP Packet Size. In the Values box, click one of the following settings:The following list shows the values you can select in the Values box:
    Setting     Description-------------------------------------------------------------Automatic   Programmatic control; this is the default settingLarge       1,500Medium      1,000Small       576						
This behavior is by design.
