Lists.GetListItems Method (Lists) - only 100 items returned

An application I'm developing against Sharepoint 2007 (MOSS) is reading from provided WebService data from a list.

http://YourURI.COM/Data/_vti_bin/Lists.asmx

Since the application is growing we get more and more items within lists.

The Method I uses were:
public XmlNode GetListItems ( string listName, string viewName, XmlNode query, XmlNode viewFields, string rowLimit, XmlNode queryOptions, string webID);

I do not add any rowLimit (null) but I were able to handel this over lists defaults.

• navigate to sharepoint
• select your list
• list settings
• All Items below Views
• manipulate Item Limit to an approperiate amount

Once I done above steps i got all my 102 entries from the list.
