我用C#写了一个连接SAP的webservice，在VS2010调试成功，发布到IIS调试就失败了。

“SAPbobsCOM”这是SAP提供的组件，
[WebMethod]
public string selectOCRD(string dbName)
{
string str = "";
DBSplPool.InitializeCompany(dbName);
if (DBSplPool.lRetCode != 0)
{
str = DBSplPool.lRetCode.ToString();
}
else
{
SAPbobsCOM.BusinessPartners BusinessPartners;
SAPbobsCOM.Recordset oRecordSet;
BusinessPartners = (SAPbobsCOM.BusinessPartners)DBSplPool.oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oBusinessPartners);
oRecordSet = (SAPbobsCOM.Recordset)DBSplPool.oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.BoRecordset);
oRecordSet.DoQuery("select CardCode,CardName from OCRD where CardCode='01'");
BusinessPartners.Browser.Recordset = oRecordSet;
str = BusinessPartners.CardCode + ":" + BusinessPartners.CardName + ":" + BusinessPartners.CardType;
}
DBSplPool.oCompany.Disconnect();
return str;
}
这是webservice接口方法

平台已经设置为X86
没有报错，
DBSplPool.InitializeCompany(dbName);

就这个地方连不上，
DBSplPool.InitializeCompany这个方法是登陆SAP用的
我的程序是运行了半个月后突然连不上的
